Xylem taps into Brazils dewatering pump demand

first_imgXylem reports that it is tapping into a growing demand within the mining and construction industry for both onsite dewatering and rental services. The company, which was spun off from ITT Corporation in October 2011, has announced that it will be expanding its dewatering rental offer in Brazil during the next three years. This year, Xylem will strengthen its dedicated dewatering rental departments in Sao Paulo, Minas Gerais and Rio de Janeiro, while the company will also launch new dewatering rental services at additional locations in 2013. Xylem’s dewatering and rental services will also be launched at a number of other locations in Brazil in 2014.Marcus Moraes, Xylem’s Manager for Dewatering & Rental Services in Brazil said: “Xylem’s new dedicated dewatering rental services in Brazil are designed to cater specifically to the needs of local customers. Each rental fleet will be organised so that it aligns with whatever specific services our local customers’ require. Xylem’s goal is to offer flexible dewatering rental services and to respond to customers’ needs as rapidly as possible. Our rental fleet now also includes the Godwin diesel surface pump which is ideal for bypassing sewer systems, drainage and large water transfer projects. The Godwin portfolio includes a full range of ‘silent’ models which is specifically designed for densely populated areas.” According to the company, there is a growing need within the market globally for expert providers of complete, turnkey dewatering solutions. While mining and construction industry businesses may have some of the technical expertise in-house that is required to manage and operate dewatering projects, more limited budgets due to challenging economic conditions, mean that they do not wish to make significant investments in equipment purchases that may just be required for a one-off project.Tomas Fernandez, Marketing Manager for Xylem’s Latin America rental & dewatering services, said, “We are noticing an increased demand within the construction industry for dewatering services to be supplied as a complete package including the pump and water treatment systems, engineering expertise and project management. The Xylem onsite dewatering service provides customers with turnkey solutions from a single source. This limits customers’ administration and management efforts and provides peace of mind as they are contracting dewatering experts to take care of the job. The beauty of the service means that customers don’t have to invest in auxiliary equipment purchases which are needed for just as long as the project requires. The capital expenditure required to purchase, maintain, service and store the equipment isn’t an issue when customers choose the onsite dewatering package. Our global sales and distribution presence means that wherever customers are located they have access to a wide range of well-maintained, world class systems and application engineering expertise.”Similarly, the pump rental market is expanding. Fernandez explained, “The pump rental option is becoming increasingly popular within the construction industry. Obviously rental is a well-established option for other types of equipment that require significant capital to purchase, however pump rental is relatively new in some markets. The rental option provides flexibility and extensive availability – customers can get access to the right product at short notice, delivered direct to the site. It also means there is no maintenance burden and the product is only costing the company while it is being used which releases capital that can be invested in other areas of the business.” Xylem’s full range of Godwin surface-mounted and Flygt submersible pumps are available to rent including the recently launched Ready pump and the expanded Flygt 2600 drainage range which now includes three sludge pumps and a two-part 2660 SH pump. With the addition in 2010 of the Godwin brand to its extensive portfolio and a rental bank of 16,000 products, Xylem now claims to offer the world’s leading range of surface-mounted and submersible pumps from one source.last_img read more

Arizona institutions to research mine safety under new grant

first_imgTo aid in improving mining safety, the University of Arizona Mel and Enid Zuckerman College of Public Health and the Lowell Institute for Mineral Resources have been awarded more than $1.3 million in funding to conduct two research projects related to mining safety. The funding was granted by the Alpha Foundation for the Improvement of Mine Safety and Health, which supports projects across the nation that are designed to improve mine health and safety. The UA funding includes a $669,208 grant to identify effective risk management interventions and a $663,817 grant to improve the effectiveness of mine safety training.Despite marked improvement over the years, mining remains a dangerous profession in the US, with 36 fatalities in 2012 and at least 20 fatalities in 2013. Some mines are safer than others, due in part to differences in their safety and health programs and training effectiveness.“Every day, mine operators across the US are challenged to ensure their employees, contractors, and vendors are highly competent with regards to safety,” said Eric Lutz, a UA Assistant Professor of Environmental and Occupational Health and Chair of the Health and Safety Committee for the Society for Mining, Metallurgy & Exploration.“These research projects will result in pragmatic tools that safety personnel and trainers can use to evaluate and improve their program effectiveness,” Lutz said.The risk management grant will be administered by lead researchers Lutz, Jeff Burgess, a UA College of Public Health Professor, and Gautam Gowrisankaran, a Professor in the Eller College of Management.Risk management programs are required in other countries but only a limited number of US mining companies follow established programs. The risk management project will evaluate the effectiveness of recent mining industry safety and health interventions in reducing injuries and injury-related costs.The training effectiveness grant will be administered by Lutz and Mary Poulton, who directs the Lowell Institute for Minerals Resources and is Head of the Department of Mining and Geological Engineering.The training research will bring together an inter-collegiate team at the UA to work with mining industry partners to provide guidance to mine safety trainers in a manner that meets US Mine Safety and Health Administration (MSHA) requirements.Lutz said the study will allow managers to evaluate their trainers and provide mine companies and regulatory agencies with a powerful tool to assess the quality of contractor or vendor-led training courses.last_img read more

Minerals4EU project meeting set for London in November

first_imgThe Minerals4EU project will be co-hosting a presentation and discussion in London, on November 11 2014, at the offices of Grant Thornton UK LLP. Minerals4EU says it “strongly believes in engaging with stakeholders at all stages, both to inform and to receive comments that will help to steer its development.” The Minerals4EU project, which is designed to meet the recommendations of the EU Raw Materials Initiative, will produce the most comprehensive and official European Minerals Yearbook as well as a foresight study on raw material supply and demand in Europe.A unique pan-European minerals knowledge data platform accessible through a web portal is being developed around an EU Mineral Intelligence Network structure, which will permanently maintain the system and mineral intelligence, and underpin the Yearbook. The system will especially enable sharing of mineral information and knowledge, and to find, view and acquire standardised and harmonised georesource and related data.Minerals4EU integrates into a leading European mineral information network structure “the best available mineral expertise and information from the unbiased knowledge base of the European national Geological Surveys and of other key stakeholders.” The Network will provide data, tools, services, and expertise to both sustain the enhancement of resource efficiency and minerals supply security, and to foster sustainable mineral development for Europe in support of public policy-making, industry, society, communication and education purposes at European and international levels. The project, which is co-financed by the European Union, is developing fast and will be concluded in 2015. Further details can be found at http://www.minerals4eu.euInvitations are being sent to senior professionals from a wide spectrum of the mining sector, together with those involved with mining in the financial, regulatory and broker communities. Senior representatives from the European Commission will be present, as will a number of management and technical staff from the project.last_img read more

Advances in hydrometallurgical copper processing

first_imgIn one of the keynote presentations at ALTA 2016 this May, Ken Baxter, VP Technology, SNC-Lavalin, Australia, asks Are we any closer to hydromet overtaking smelting for copper sulphide concentrates? The abstract follows.Where primary copper concentrates contain little in the way of deleterious elements and transport or government royalties for export of untreated concentrates do not present significant commercial issues, smelting of primary copper concentrates remains the route of choice. Opportunities for technically viable hydrometallurgical treatment routes ultimately turn on commercial viability and an assessment of risk for hydrometallurgical options.While pyrometallurgical treatment of concentrates is capital intensive and has stringent environmental controls, smelting technology also continues to evolve to address these issues, so it is unlikely that primary sulphide concentrate treatment will move significantly away from smelting unless concentrate compositions change significantly. However, increases in the proportion of concentrates produced with high levels of impurities will increasingly open opportunities for hydrometallurgical flowsheets to be considered.Most primary hydrometallurgical options for treating both clean and dirty primary copper concentrates remain commercially unproven, although there are an increasing number of process plants treating primary and secondary copper concentrates where the hydrometallurgical process can add value to the project that cannot be achieved via a concentrate smelting route.For secondary copper concentrates, the alternatives are much more open, with a significant number of hydrometallurgical plants in operation treating both concentrates and run of mine ores ROM. Whole ore treatment is prevalent as a result of difficulties in obtaining good flotation recoveries.This paper will explore the basis of flowsheet selection, in cases where alternatives other than smelting have been considered for copper sulphide concentrate treatment.last_img read more

W Resources selects Sandvik crusher for La Parrilla tungsten mine

first_imgW Resources Plc, the tungsten, copper and gold mining, production, exploration and development company with assets in Spain and Portugal, is pleased to provide an update on equipment finance, grants and development for its flagship La Parrilla tungsten mine in Spain.Significant progress has been made on financing for the next development phase at La Parrilla mine to achieve 1.95 Mt/y ROM and 2,500 t of tungsten concentrate production. Terms have now been agreed with leading vendors for the financing, supply and installation for two of the three core equipment packages: the crusher and jig/mill plants.It is expected that vendor finance of 50% will be provided on the crusher and jig/mill plants and formal contracts are expected to be awarded in the next month. For both of these equipment packages, W has applied for grants from the Extremadura Regional Government in Spain for between 20% and 30% of the value of this equipment. W will also apply for grants for the third core equipment package, La Parrilla concentrator. Arrangements for the financing of La Parrilla are advancing well and are expected to include a convertible note to fund the balance of the plant packages.The new state of the art Sandvik crusher is expected to be installed by mid-2017 which should result in a very substantial reduction in crusher costs of the order of $50/mtu compared with the current mobile plant crushing costs. The crusher package is designed to minimise the production of tungsten fines, which are harder to recover than more coarse material. Given the potential for very significant operating cost reductions and recovery improvements from a new fixed crushing circuit, the Board and operations team have evaluated the most strategic production options and elected to temporarily halt production, with a view to restarting operations following installation of the new more cost-efficient crushing circuit.During the 2016 production runs, the company made substantial progress improving the design of its primary plant and looks forward to restarting later in 2017 with a significantly lower cost structure.In addition, the significant engineering effort that has gone into the design of both the crusher and jig/mill plants will allow both Plants to be expanded from 1.95 Mt/y ROM mine ore feed to 3.5 Mt/y ROM at low incremental cost and with minimum plant shut down time.Overall financing of La Parrilla is advancing well:The equipment finance packages will provide 50% funding for key plantGrants have been applied for and have the potential to fund a further 20-30% of these packagesFunding negotiations have advanced to provide a convertible note to fund the balance of funding for the plant packagesMichael Masterman, Chairman of W Resources: “It is very encouraging to see tangible progress on both the development and finance fronts at La Parrilla. Our suppliers and engineers have made significant progress to greatly enhance the integrity and expansion potential of our core equipment. We are in a strong position to significantly advance financing and development in the first half of 2017.”This and scores more projects are examined in the January 20 issue of International Mining Project News – emma@im-mining.com for subscription informationlast_img read more

Green Vale iron ore vessel loads for the first time at Tubarão

first_imgThe first second-generation Very Large Ore Carrier (VLOC) loaded for the first time this week at the port of Tubarão, in Vitória, Espírito Santo, Brazil. The vessel, Yuan He Hai, with a capacity of 400,000 t, is the first to come into operation of a total of 32 under construction to serve the seaborne iron ore trade, particularly in the Brazil-China route. The new VLOCs, more efficient and sustainable, are being built with Vale’s support, maintaining the company’s maritime transportation of cargoes as one of the most efficient in the world in terms of greenhouse gas emissions.The new vessels will emit between 15% and 20% less carbon dioxide than the existing Valemaxes, considered as the first generation, which have been in operation since 2011. The Valemaxes, a pioneer project by Vale, emit 35% less carbon dioxide compared to capesize vessels, which were the standard ships for iron ore transportation, with carrying capacity of 180,000 t. The Yuan He Hai docked at Tubarão port last Sunday, February 25, and took one and a half days to load before departing to Asia.The remaining 31 vessels of 400,000 t will be delivered to shipowners by the end of 2019. In addition, Vale is negotiating contracts which will result in the construction of new 325,000 t ships, called Guaibamax. “We believe these vessels incorporate the state of art in terms of efficiency and environmental innovation in this field. The Guaibamax, for example, will also be equipped with scrubbers which will allow for elimination of up 99% of sulphur emissions into the atmosphere”, says Vale’s Shipping director, Renata Costa. Between 70% and 74% of the large vessels (in other words, vessels with a capacity of over 180,000 t) that transport cargo for Vale are used in the Brazil-China route.last_img read more

Hecla outlines its future mining plans with Epiroc Mobile Miner technology

first_imgAt the SME event in Minneapolis recently, Hecla Mining presented a paper in the Technical Program entitled Hecla’s Mobile Mechanical Vein Miner. Hecla’s Lucky Friday is an underground silver-lead-zinc mine that has been in operation for 75 years and produces from depths over 2.3 km below the surface. Technical issues at this depth include high rock temperature and seismicity. The Lucky Friday stress magnitude at depth is roughly similar to significantly deeper South African gold operations.The use of new innovative mechanisation is being examined for ore production. Principal advantages of mechanisation are the reduced exposure of personnel, reduced seismic triggers, and increased efficiency. Lucky Friday has partnered with Epiroc to design, build, test, and deploy a mechanical miner, the Mobile Miner 40V, for primary ore production.The primary mining method employed at the Lucky Friday mine since its inception is cut and fill. Prior to the 1980s, overhand cut and fill with hydraulic sand backfill was used. To minimise the size and occurrence of the seismicity, the advance line of the stopes was altered to a staggered pyramid or stair-step shape. Although the overhand stope advance geometry change reduced the magnitude of seismic events, it did not totally prevent them since pillars were still created. A study aimed at reduction in the seismic hazard was conducted in the late 1970s, with a recommendation to convert the method to a mechanised underhand approach. In the early 1980s, the mining method was changed accordingly, utilising an engineered cemented paste fill back. The method, termed the Lucky Friday Underhand Longwall (LFUL) converted the stope access from captive in-vein raises to a series of footwall spiral ramps with slotting to the vein. The original objective of the method was to create a downward-advancing longwall that would eliminate pillars and continuously shunt the stresses to abutments in advance of mining. This method is still currently in use and has been successful in reducing seismic occurrence and event magnitude through minimising the creation of pillars and reduction in the exposure of miners to the stope face area. The engineered cemented paste fill back has been very successful in improving stope ground conditions. In the mid-1990s, a major new vein (the 30 Vein) was discovered at depth beneath the historic Gold Hunter mine – about 1.6 km northwest of the Lucky Friday mine. Whereas the host rock mass at the Lucky Friday was a brittle and strong siliceous quartzite (the Revett formation), the 30 Vein is in weaker and heavily foliated argillite.All mining activity was transferred from the Lucky Friday vein to the 30 Vein (and associated parallel veins) in the late 1990s, with access to the 30 Vein via horizontal haulage drives from the Silver Shaft at the 4900 and 5900 Levels. The shallower depth and lithologic change to a weaker, more deformable rock mass resulted in a significant reduction in seismicity. At the current time, mining has progressed down-dip to approximately the 6300 Level, 2.2 km below surface. Exploration drilling below the advancing mining front has identified a prominent widening 30 Vein resource with increasing silver and base metal grades. The current reserve has been identified to about 7600 level and has been intercepted at over 8000 level. To exploit this deep resource, a decision was made in 2009 to begin construction on a winze from the 4760 Level to the 8620 Level (2.9 km) depth. This shaft was completed in January 2017.It was determined that, to ensure viability of the mining of the 30 Vein to such great depth, a revision of the current underhand mining method was necessary to minimise seismic potential as well as exposure of workers to increased heat and diesel particulates. An internal Hecla study was conducted to first identify overall criteria for the method, and to then develop a mining concept. The criteria identified were as follows:• Minimise seismic potential by: elimination of pillars using a true underhand longwall to bottom-slice the 30 Vein, and, through use of an incremental, continuous mechanical mining method that eliminates in-stope blasting that may trigger remote fault-slip movement• Eliminate diesel particulates and reduce heat rejection to the ventilation by implementing battery and electric equipment to the extent possible. Ultimately, this will minimise refrigeration requirements and increasing ventilation demand• Remove workers from in-stope conditions to the extent possible by using state-of-the-art tele-remote and autonomous operationsBased on these criteria, Hecla entered into discussions with numerous equipment OEMs for development of a specially-purposed mechanical Mobile Miner that could cut the relatively weak and moderately-abrasive vertical veins. Mechanical cutting is facilitated by the relatively-uniform width of the 30 Vein and the predictable verticality and straightness (no offsets) of the vein over its 760 m strike length. Atlas Copco (now Epiroc) was selected as a partner in this project due to its long-term development of steel disc-based (TBM) Mobile Miner technology (including a similar unit in current testing) and its willingness to share in development engineering and testing costs. A set of design and operational criteria were developed for the Mobile Miner based on:• Advance rate (ft/day/machine)• Mining width and height• Manoeuverability (turning radius) and negotiable grade• Operation within the constraints of the current underhand mining system with engineered paste fill roof• Tele-remote (non-tethered) operation and automated facecutting operations• On-board bolter for wall bolting and meshing (roof presupported) with goal of eventual automation• Wall collision detection and guidance assist• High definition cameras for face viewingConfirmation of the cutability of the 30 Vein “package”, which consists of sulphide ore and gangue material of siderite (iron carbonate) and argillite was confirmed via linear cutter testing on large blocks of vein package material at the Earth Mechanics Institute of the Colorado School of Mines. This testing, using standard 17” steel disc cutters showed relatively easy cutting and spalling of rock chips using 75 to 100 mm (3 to 4 in) cutter spacings and moderate applied cutter forces. Additionally, due to the moderate abrasivity of the vein, cutter wear is expected to be low. An approximate 1½ year design program was initiated in 2015, culminating in completion of the design in early 2018 with manufacturing scheduled to be completed by early 2019. Currently, it is estimated that a 5-month testing phase will be conducted in a test mine at the manufacturer’s site, followed by shipment, re-assembly and proof-of-concept at the Lucky Friday mine starting in early 2020.The Mobile Miner consists of two major parts; the rear “power unit” and the front “miner.” The miner part incorporates the cutterhead and everything needed to excavate ore; the power module contains all the motors, pumps, ground support and control systems. Each unit is roughly 10 m in length. The two parts are connected by an articulation joint to improve manoeuverability for negotiation of tight corners as well as minimise vibration at the operator’s cab. The miner has two track units and the power unit one twin track that can be controlled separately. To obtain better steering control of the power unit, the track is mounted on a slewing bearing allowing the trailer to swing sideways when the tracks are slewed 90°.  The “miner” part consists of the thrust module, with cutterhead and front frame. During cutting, the thrust module moves the cutterhead in a forward, up-down or slewing motion while the front frame remains gripped to the excavation.The power system has two different modes, high power with 4160 V and low power with 480 V. The power for cutting is approximately ten times higher than what is needed for tramming. The motor control center is placed outside the stope on the sublevel of the ramp access to provide for a well ventilated, temperature controlled, accessible location. The Mobile Miner is equipped with a Rig Control System (RCS). This is a computerized control system based on CAN-bus technology. RCS is used for most communication and steering of actuators, sensors, lights and can also be used for remote control of the machine. RCS also has capability to log data if needed.The Hecla Mobile Miner Project is divided into six Phases: Phase 1 – Pre-Feasibility Study; Phase 2 – Feasibility Study; Phase 3 – Design; Phase 4 – Manufacture and Testing; Phase 5 – Test Trial at Epiroc test mine; Phase 6 – Field Trial at Lucky Friday mine The project is currently in Phase 4.The implementation plan of the Mobile Miner is envisioned to be in two phases. The first phase of implementation is to establish a true longwall face across the entire 30 Vein by advancing 12 stope to the same elevation as the adjacent stopes. Since advance rates for the Mobile Miner are expected to be significantly faster than drill and blast, it is expected that the longwall can be achieved in roughly three years’ time. The second phase will be implementation of two machines bottom slicing the full minable strike length of the 30 Vein.Phase 2 implementation will allow for a higher utilisation of the ore face by dedicating the full strike length to the machine and allowing nonmining activities to occur behind the advancing ore face. As the miner exits the vein, it will move out through the slot to the sublevel and loop back around to start the next cut. It is planned to utilise two machines mining on successive, staggered horizontal cuts with a lead/lag of approximately 300 m. This means that the lower miner will be excavating beneath paste fill placed behind the upper miner. Backfilling of the vein will be done behind the advancing Mobile Miner after it has passed each slot access point (and a new stope entry/exit is established), thereby removing backfill activity from the critical path of ore mining.last_img read more

Agnico Eagle Nunavut projects progressing well

first_imgAgnico Eagle Mines provides an update on activities at its 100% owned Nunavut projects.  These include the Amaruq project, which is located approximately 50 km northwest of the Meadowbank mine, and the Meliadine project, which is located approximately 25 km from Rankin Inlet.  Highlights include:• Type A water licence received for the Whale Tail pit at the Amaruq project – On July 11, 2018, the Type A water licence was approved by the Minister of Crown-Indigenous Relations and Northern Affairs Canada.  This permit allows for the construction and development of the Whale Tail pit• Preliminary construction work and stripping of the Whale Tail pit will begin in the third quarter of 2018 as expected – The Whale Tail deposit remains on schedule and budget for the start of production in the third quarter of 2019• The Whale Tail underground exploration ramp is proceeding as planned – At the end of June 2018, approximately 478 m of ramp development had been completed at a cost of approximately $10.7 million.  In 2018, approximately 1.2 km of ramp development is planned• Amaruq exploration drilling continues to expand known mineralized zones – Recent drilling intersected 10.2 g/t Au over 16.9 m at 316 m depth, confirming the grade and geometry in the Whale Tail ore shoot.  A recent hole in the V Zone returned 10.3 g/t Au over 5.0 m at 20 m depth, which is expected to extend mineral resources westward at surface• Meliadine project proceeding on schedule and on budget – Development activities remain on track for the commencement of production at the Meliadine project in the second quarter of 2019.  The first boat of the 2018 shipping season has been off-loaded at Rankin Inlet, and additional boats are expected in the coming weeks“We would like to thank the various regulatory agencies, both federal and territorial, the Inuit Organizations, the local communities and our employees for their diligent participation in the permitting process.  With the approval of the Whale Tail Type A Licence, the project remains on schedule to commence production in the third quarter of 2019, and exploration activities continue to expand the known mineralization, which could potentially extend the mine life”, said Sean Boyd, Agnico Eagle’s Chief Executive Officer.“Elsewhere in Nunavut, development activities at Meliadine are progressing on schedule and on budget, which continues to support the start of production in the second quarter of 2019”, added Boyd.Agnico Eagle has a 100% interest in the Amaruq project, northwest of the Meadowbank mine. Amaruq is situated on a 99,878-ha property, almost adjacent to the 68,735-ha Meadowbank property.  Development of the Amaruq project was approved in February 2017 by the Company’s Board of Directors as a satellite deposit to supply ore to the existing Meadowbank mill, pending the receipt of the required permits.In late July 2018, the company plans to initiate construction of the Whale Tail dike (rock fill has already been stockpiled for use as per approval within the pre-development license) and begin progressive overburden and waste stripping for Phase 1 of the Whale Tail Pit.‎The schedule for construction activities, including Whale Tail Lake dewatering, is expected to allow for progressive mining and stockpiling of ore in the second quarter of 2019 to support the expected start of production in the third quarter of 2019, which will coincide with the end of production at the Meadowbank mine in 2019.The Amaruq project remains on budget with capital expenditures in 2018 forecast to be approximately $175 million. During the second quarter of 2018, Amaruq site activities focused on:• Underground ramp development, which advanced by 350 m in the quarter• Detailed engineering studies for Whale Tail infrastructure (87% complete)• Expansion of the temporary camp facility and completion of a maintenance shop for mining equipment• Expansion of the exploration road to a production haulage road, which began in April 2018.Exploration continues at depth in both the Whale Tail deposit and V Zone, as well as conversion drilling of underground mineral resources at Whale Tail closer to the planned pit bottom.  In addition, several rotary air blast drill holes were completed east of Mammoth to test a magnetic anomaly.The Whale Tail deposit has been defined over at least 2.3 km of strike length and extends from surface to 915 m depth.Exploration continues at depth with the aim of extending the limits of the deeper mineral resources.  In the shallower parts of the underground mineral resources, closer to the planned pit bottom, infill drilling is occurring from surface.  The objective is to improve the understanding of the geometry and limits of the main Whale Tail ore shoot.  The current understanding is that the Whale Tail ore shoot stretches from surface to almost 550 m depth over a strike length of approximately 1,500 m, following a shallowly east- to northeast-plunging fold hinge in the mineralized chert-iron formation sequence.  The results should allow a more rapid assessment of the economic potential of this area.The Whale Tail deposit remains open at depth.  The drill program for the remainder of 2018 will continue to test the Whale Tail deposit and the parallel structure to its north at depth, to expand the mineral resources and continue to convert inferred mineral resources to indicated mineral resources.The V Zone consists of a series of parallel stacked mineralized structures striking northeast from near surface to as deep as 653 m below surface; the dip of the structures ranges from 30 degrees near surface to more complex geometry at depth.A mineralized corridor 100 to 150 m wide plunging shallowly to the northeast has recently been interpreted as a V Zone ore shoot at depth.  It extends from approximately 300 m to more than 650 m depth.  The V Zone ore shoot follows the south limb of a fold in the contact between volcanic and sedimentary rock units, which is a favourable location for mineralization.  While the V Zone ore shoot is approximately parallel to the Whale Tail ore shoot, it is offset approximately 200 m to the northwest and occupies a different stratigraphic horizon.  Most of the recent results are from the deep part of the V Zone structures.Significant gold grades are being encountered along multiple stacked mineralized horizons associated with the V Zone ore shoot described above.  These mineralized zones are hosted within both the volcanic and sedimentary rocks, contributing to contrasting styles of mineralization.  Volcanic host rocks result in ore styles typical of what is observed in the V Zones close to surface (a series of discrete shear veins), while sedimentary host rocks result in mineralization styles more typical of the Whale Tail type of mineralization (a mix of more diffuse veins and silica flooding within greywackes and chert units).  The latter style of mineralization is characterized by less nugget effect and often a wider and generally more predictable gold distribution.Drilling will continue in the V Zone to test its depth and lateral extent.The Meliadine project was acquired in July 2010, and is Agnico Eagle’s largest gold deposit in terms of mineral resources.  The company owns 100% of the 111,358 ha property.  In February 2017, the Board of Directors approved the construction of the Meliadine project.Underground development and surface construction at Meliadine continued through the second quarter of 2018 and the project remains on schedule and on budget for the commencement of production in the second quarter of 2019.  The estimated capital budget for 2018 is unchanged at $398 million.On July 9, 2018, the first vessel of the sealift shipping season arrived in Rankin Inlet.  The first boat has been unloaded and a second boat is in position to begin its off-loading.  Additional details on the Meliadine project will be provided in the Company’s news release reporting second quarter 2018 results, which is scheduled for release on July 25, 2018.last_img read more

Sandvik developing AutoMine® Access API for interoperability

first_imgSandvik Mining and Rock Technology has announced it will develop an interoperable platform for its world-leading automation system for underground loaders and trucks – AutoMine® at #DisruptMining, an event focused on fostering new technology in the mining industry.“As a world leader in underground automation, we have a responsibility to make this game-changing technology easier to implement for the mining industry,” said Patrick Murphy, President Rock Drills & Technologies, Sandvik Mining and Rock Technology. “While we feel that customers will achieve the highest level of performance when purchasing Sandvik equipment, we recognize the need to unlock automation’s full potential for all equipment regardless of manufacturer. Customers with mixed fleets will have the full power of AutoMine® behind them as well.”To enable interoperability, Sandvik Mining and Rock Technology will introduce the AutoMine® Access API which will provide standard, pre-defined interfaces for connecting third party loaders and trucks for control by Sandvik’s AutoMine® system. An API (Application Programming Interface) is a set of functions and procedures that allows the creation of applications that access the features or data of an operating system, application, or other service.In addition to APIs, to be compatible with AutoMine®, third party equipment designs must conform to the functional safety requirements specified for AutoMine®. “This API is another step in Sandvik’s journey to drive a digital ecosystem that makes mining smarter, safer and more efficient.”Sandvik Mining and Rock Technology released its Interoperability Policy in April 2018, outlining the principles by which Sandvik systems can communicate within a digital ecosystem including data accessibility, fleet data compatibility, data rights and control, and data privacy. “The addition of AutoMine® for underground loaders and trucks to this policy is the next step in Sandvik’s continued journey to set the industry standard for mine automation and digitalisation.”“Sandvik has been leading the market in automation for decades, with more than 400 pieces of equipment using AutoMine® around the world without an injury,” said Murphy. “As more customers embark on their digital journeys, interoperability will be a requirement. We are proud to leverage our experience to drive digitalisation further in the mining industry.”last_img read more

SEHA derby RK Zagreb with a point from Skopje

← Previous Story Ahlm suffers knee injury – Dragicevic will get a chance Next Story → Dutch youngstar, Angela Malestein: “I want to reach everything” The derby between the best teams so far in the SEHA league, RK Zagreb and RK Metalurg which was played in Skopje, gave us no winner, and therefore Metalurg and RK Zagreb remain on top of the league with same amount of points. As for the game, RK Zagreb had the led only during the first half – 4:3 the most, which was low-scoring one, and then Metalurg takes over the game lead and has 6:4 and 8:6, but both teams go to half break with 8:8, Balic scoring in the last second of the game. In the 2nd half, Metalurg began strong, making 5 goals lead for a 15:10 lead. Then Metalurg had to do with a player less for 8 minutes, and this gave Zagreb the chance and they took it and got to 17:17 in the 57th minute. The goal-for-goal game continued until the end of the game, and the game ended 19:19. Topscorer for the hosts was Mojsovski with 7 goals, while Stanic had 11 saves. For the visitors, Vukic and Kopljar had 4 goals each. In addition, the hosts had numerous complaints about the refereeing of the Bosnia and Herzegovina referees.photo: rkmetalurg.mk read more
