Researchers from the Sustainable Minerals Institute’s Julius Kruttschnitt Mineral Research Centre (JKMRC) say they are developing a soft sensor to overcome previously-accepted performance challenges facing SAG mills. SAG mills are a key asset for mineral processing operations as one of the critical stages of extracting mineral out of ore, and their continued stable operation is[…]

Weba Chute Systems’ Wade Vandenberg says mines across Africa are recognising the value of the company’s custom-designed chutes in controlling material flow, extending wear life and reducing maintenance downtime. The South Africa-based company’s transfer point solutions have made their way into mines across Africa, from platinum to diamond operations, to gold, coal and copper mines.[…]

Kwatani has once again shown its mineral processing expertise in a retrofit project that saw one of the largest coal processing plants in South Africa boost screening throughput. The South Africa-based company was brought in to consult on possible solutions to assist the plant in not only returning its screening throughput performance to the original[…]

Itronics says test work on two separate precious metals closed heap leach materials pads has provided positive results in recovering metals and minerals using its proprietary “Zero Waste” technologies. Rock Kleen Tailings Processing Technology neutralises the residual cyanide and removes nitrogen produced by blasting rocks in the mining process, making the materials available for use[…]

DRA Global says it is in the final stages of the implementation of the engineering procurement and construction (EPC) of the gold concentrate plant for Diversified Minerals’ Dargues gold project, in New South Wales, Australia. The engineering company was awarded the EPC contract back in January 2019 after detailed design for the project commenced in[…]

Mexico has become the latest country to enforce a suspension of non-essential activities in response to the outbreak of the COVID-19 pandemic, with its Ministry of Health ordering a temporary halt of activities until April 30 in order to slow the virus spread. Mexico is the world’s largest silver producer, having produced 6,300 t of[…]

As ore grades continue to decline in the mining space, FLSmidth says its expertise in mineral sampling and laboratory automation is becoming increasingly valuable to mines. “The more you understand about the characteristics of the ore entering your process plant, the better you can treat it,” Martin Matthysen, Director, SPA (sampling, preparation and analysis), Sub[…]

Vale says it is evaluating short-term alternatives to the wet processing of tailings at its Brucutu iron ore mine, in Brazil, as it looks to step up processing activities at the Minas Gerais operation. The Brucutu plant, which used to dispose of tailings in the Norte/Laranjeiras dam – that has been at “emergency level 1”[…]

Bis, FLSmidth and Karara Mining have developed a “unique mobile stacking conveyor” solution that has cut water use, costs and the environmental footprint at the iron ore miner’s operation in Western Australia. If Karara’s iron ore mine had chosen a wet tailings storage facility, the tailings pond would have been roughly 8 sq.km based on[…]

McLanahan Corporation says it continues its long-standing support of Indonesian coal projects after being awarded a A$4.5 million contract to supply custom-engineered feeder breakers to PT Bukit Asam for an expansion at one of its mines. PT Bukit Asam’s main sites are the Air Laya, Muara Tiga Besar North and West & Central Banko mines[…]
