The US Department of Energy (DOE) has released $500,000 in federal funding that will allow a team from West Virginia University (WVU) to participate in a $1.3 million US-China coal-to-liquids project. The funding will allow WVU scientiststo study the economic and environmental effects of coal liquefaction technology and develop expertise regarding the commercial deployment of advanced coal technology through their participation in the three-year project between DOE and China’s National Development and Reform Commission.Commenting on this: “For too long, the US has let itself grow dependent on oil from the Middle East. We must break that addiction,” US Senator Byrd said in an April 19 press release. “Coal offers us a great opportunity to break the chain of foreign energy dependence. The technology is ready today to convert coal to transportation fuels. It is common sense that we rely on our domestic resources to handle our domestic fuel demands.” He said the funding will allow WVU experts to share knowledge with their Chinese counterparts and gain insights that will help further develop coal liquefaction in the USA. “The Chinese recognize that foreign oil won’t be able to handle that nation’s kingsize energy needs, and, like the US, China is looking to coal as an alternative,” he said.
A number of ridiculous NGOs, not least Alburnus Maior have, ignoring science and best practice in environmental remediation, been fighting Gabriel Resources’ plans to clean up old, very environmentally unsound mine workings in the Rosia Montana and develop a modern, clean gold mine. Sadly, now their idiotic campaign is going to lose many sorely needed jobs, lose some people their homes and bring a stop to important archealogical work. The latest threat is a cyanide ban in Romania.Deep drilling at Red Chris has confirmed the expansion of the mineralised system at this copper/gold project in British Columbia. Among the news of mine starts in the last couple of weeks are Minera Corona starting treatment of silver-lead ore at its new oxide plant in the Yaulicocha province of Lima department, Peru.

Sepro Mineral Systems Corp is now offering an enhancement in design for the Semi-Batch 5200B Falcon Concentrator rotor bowl lining. The LSP insert has demonstrated significantly improved wear resistance during equipment operation. After a recent and extensive six-month R&D project, it was confirmed through field trial testing that the LSP insert provided greater wear resistance over rubber and ceramic lining under harsh wear conditions.Gerry Barstad, Chief Metallurgist – Detour Gold – explains: “Detour Gold ore has extremely aggressive wear characteristics for processing equipment and piping so we originally specified ceramic tile lining in our SB5200B Falcon Concentrators and associated piping. Sepro offered to develop an improved rotor bowl lining system to help extend wear life and reduce operating costs. The resulting moulded rubber Lower Strike Point insert ring is lasting about one-and-a-half to two times longer than the original ceramic tiles and knocks into place without removing the bowl. It effectively relines the lower bowl impact wear area very quickly and has demonstrated significant improvement in wear and reduced maintenance costs.I would highly recommend the new LSP Insert lining system for Falcon 5200B Concentrators to other gravity gold recovery operations.”Sepro is making the LSP insert available to all current Falcon SB5200B owners as a low cost retro-fit parts package. All new SB5200B units sold will incorporate this latest enhancement as the design standard. Sepro is developing plans to release the LSP Insert for the SB2500B Falcon model in the near future.
ABB has re-packaged its proven and tested service offering for gearless mill drives (GMD) remote diagnostic services with the launch of a newly created product package of two modules, GMDbeatTM and GMDfitTM. The basic module, GMDbeat, covers ABB’s SupportLine and online troubleshooting while the enhanced module, GMDfit, offers online condition monitoring, predictive analytics and periodic health checks from ABB system experts. The product will initially be launched in Peru and Chile, with other countries to follow in 2015.“By combining separate service offerings into one package we can support our customers with a holistic approach,” said Remy Lanoue, Global Head of Service Mining, “This integrated service concept combines the past, the present and the future by utilizing system health checks, on-demand remote support and condition monitoring. It leverages the main advantages of each service to add more value to our customers.”Earlier these services were all offered separately. Now they are packaged into one comprehensive offering including GMDbeat and GMDfit to combine remote connectivity, advanced monitoring and analysis tools with global technical expert support via a secure remote connection for faster response. In the case of a critical machine condition a notification is still sent to ABB and the customer’s maintenance team however now the incident is handled as a prioritized SupportLine case, even if no actual system failure occurs. Therefore, the two modules – GMDbeat and GMDfit – perfectly complement each other to ensure system availability and to increase the overall equipment effectiveness (OEE) of the GMD system.The new package also brings additional features such as full control over the data and analysis tools for customers. They can now generate reports by themselves and easily access the data from any location in the world using ABB’s user-friendly, web-based application.ABB’s expertise in the mining industry includes engineering GMDs for the largest autogenous (AG), semiautogenous (SAG) and ball mills in the world that also fulfil highest power requirements and are ready to operate under extreme environmental conditions. Since designing its first gearless mill drive in the late 1960s, ABB has accumulated over forty years of experience in optimizing gearless solutions for grinding applications. ABB says its GMD “is the most powerful mill drive system on the market.”

The following statement was released last week by National Mining Association (NMA) President and CEO Hal Quinn applauding the introduction of Senate Energy Committee Chairwoman Lisa Murkowski’s (R-Alaska) bill, the Mineral Security and Manufacturing Competitiveness Act of 2015, to secure the nation’s mineral supply chain and reduce its growing dependence on imported minerals critical for manufacturing industries:“Senator Murkowski’s bill will modernise the permitting system for US mining to better position our country to meet the challenges of the 21st century. Simply, her bill will better prepare our country to meet the competitive challenges we face in strengthening future economic growth and the US manufacturing revival.“While few countries can rival our abundance of mineral resources, even fewer have a permitting system as inefficient as the US. Our antiquated and duplicative permitting process discourages investment and jeopardises the growth of downstream industries, related jobs and technological innovation that all depend on a secure and reliable mineral supply chain.“Our country’s dependence on mineral imports has doubled over the past 20 years. Today, less than half of the mineral needs of US manufacturing are met from domestically mined minerals. These trends will only worsen if we do not advance policies that enable US mining to perform to its potential.“America’s manufacturing CEOs have recognised that using our country’s minerals responsibly and efficiently is a national priority for strengthening our manufacturing base and the jobs it provides. Competing countries are acting boldly to secure use of these minerals. It is time our government acted accordingly.“Without compromising our rigorous environmental standards, this legislation helps reduce the inefficiencies of our underperforming permitting system by incorporating best practices for improving coordination among state and federal agencies and clarifying responsibilities – all necessary to bring accountability to the process. NMA urges support for American minerals and Sen. Murkowski’s far-sighted leg
Marthinusen & Coutts recently performed an extensive rehabilitation of an old 2,985 kW salient pole synchronous mill motor that hadn’t been in use for over 10 years. The project was commissioned by international mining company Newmont for the Waihi opencast gold mine in New Zealand. Marthinusen & Coutts took on the project after initially agreeing to retrieve the motor from where it had been left lying in the veld at the site of the old Crocodile River gold mine at Hartebeespoort Dam near Skeerpoort, Gauteng, South Africa.“We were first awarded a contract to assess the condition of the motor to establish what sort of state it was in and to then quote for repairing it,” Craig Megannon, General Manager at Marthinusen & Coutts, says. “Not surprisingly we found it to be in a poor state. Apart from the fact that it had been left abandoned for so many years, it is a very old motor. It was manufactured in Japan in 1970 and had since been deployed at mining operations in Australia, Argentina and South Africa.“Repairing it has involved an extensive amount of work and included complete remanufacture of parts that we found to be beyond repair,” Megannon says. The rehabilitation contract was awarded in October 2014 and was completed at the end of October 2015. The repairs that were done included rewinding of the rotor, replacement of the stator core with laminations manufactured by Electrical Machines’ Laminations & Tooling business unit. Parts that were replaced with re-manufactured parts included the journals, slip-rings, brush gear and coupling.“We also modified the stator design to increase the stator copper thickness and reduce the overall tem¬perature rise, which we found to be the main limiting factor in the stator in its original form. We did the design using advanced software we recently acquired for this type of specialised work,” he explains.Machine Monitor, an Australia-based third party engineering company, observed and monitored the entire rehabilitation process and testing at Marthinusen & Coutts’ Cleveland plant throughout the duration of the contract on Newmont’s behalf.The picture shows Marthinusen & Coutts’s test technician, Suresh Gunpat, with the 40 pole synchronous mill motor during the series of tests conducted on it on completion of the rehabilitation process.
Caterpillar now offers factory installed fire suppression systems on certain models of Cat® surface mining equipment. The integrated designs by Caterpillar engineers help ensure high reliability and extended durability of the systems. The factory installation option also speeds machine delivery by cutting time required for field installation. Current Cat machines offered with factory installed fire suppression systems include the D10T2 dozer and the 777G off-highway truck. Plans call for offering the factory installed systems on additional Cat mining machines, such as the D11T dozer. For these machines, the Ansul® Checkfire 210 Detection and Actuation system is installed with the Ansul LVS liquid agent fire suppression system. The LVS fire suppression system agent provides both fire suppression and superior cooling of superheated surfaces while blanketing the fuel and cutting off oxygen to help prevent reflash. Caterpillar and Ansul personnel worked closely to optimize system configurations and validate spray coverage. Caterpillar design integration ensures that adequate and structurally validated space is allotted per Caterpillar engineering standards for routing and securely mounting fire suppression system components—detection wire, suppressant lines and nozzles. And factory installation eliminates days of disassembly and reassembly work for installation of hardware. For example, factory installed fire suppression can put a D10T2 to work about three days faster. On-site certification by an authorized Ansul distributor is required after machine commissioning.
Three new 2018 Cat® articulated trucks—730, 730 EJ (Ejector), and 735—replace their C Series predecessors and offer new operator stations, transmission-protection features, a new hoist-assist system, an advanced traction control system, new stability-assist system, and a fuel-saving ECO operating mode. The 730 and 730 EJ have 28 t payload capacity and the 735 has 32 t. This class of machines is widespread in in small mines, sand and gravel operations and in mine construction, such as through earthmoving contractors.The new 730 and 730 EJ are also enhanced with automatic retarder control and a hill-start feature. The 735 retains these features from the C Series model and further incorporates a new Cat C13 ACERT™ engine, Cat CX31 transmission and structural and dimensional modifications that reduce empty weight by 22%. These features combine for a fuel efficiency gain of as much as 18% while retaining the productivity of the previous model.A new combined transmission-and-hoist lever provides efficient, single-lever control of vehicle speed and body-hoisting functions to reduce operator effort and to automate repetitive operations. The standard Cat Detect/Stability-Assist system monitors the working angle of the tractor and body, as well as the grade, and cautions the operator if the machine is approaching the set threshold angle, stopping the dump process if continued action may result in potential tipping. The 730 EJ is designed to eject loads while traveling, providing positive dumping of the entire load, even when the material is sticky.Further enhancing safe operation is the Advanced Automatic Traction Control system, which features refined technology for proactively applying differential locks to avoid wheel spin. Also, a throttle-smoothing system prevents acceleration surges when traveling over extremely rough terrain. The optional Cat Connect PAYLOAD technology calculates payload via sensors on the suspension, and load-status lights at all four corners of the cab roof ensure visibility to the loader operator from any angle.The C13 engine used in all the new trucks is available in configurations to meet emissions standards in all regions of the world.
In 2018, Nordgold’s Bissa gold mine in Burkina Faso has successfully commissioned a Wenco Fleet Management System (FMS). This has helped to further increase the mine’s efficiency and safety. “FMS ensures 24/7 operations control via a modern dispatch system. This can surveil the entire Bissa-Bouly hub operations in real-time mode, as well as calling the supervisors to improve the fleet traffic. All these measures not only increases efficiency, but helps avoid traffic accidents.”Wenco solutions are installed on the loading and hauling fleet, and auxiliary equipment. Wenco is integrated with SAP to allow the sharing of data between the fleet management and enterprise resource planning systems. One focus area is on optimising their loader utilisation at the crusher where the loader would load from different material stockpiles directly into the crusher. This is anticipated to greatly improve plant output. Spotters at the loading area use “toughpads” to connect directly to Wenco in the loader to assist the operator with loading material.Bissa is a world class mine launched in January 2013. The mine reached industrial scales of production within the first month of operation and full capacity after only 6 months. Bissa mine fully paid back the investment within 21 months after the launch. Nordgold expanded its flagship Bissa mine with the launch of a heap leach operation at the nearby Bouly deposit in September 2016. The Bouly mine reached full production capacity in just two month after launch. Bissa produced 195,700 oz of gold in 2017 and Bouly 124,200 oz.
