IsaMill technology was developed from the stirred milling technology of Netzsch Feinmahltechnik in the 1990's for use in the fine grained lead zinc ore bodies of Northern Australia in a drive to bring about a step change in grinding efficiency required to make these ore bodies economic to process. The following two decades have seen the ...
Vista Gold has turned to TOMRA Sorting Mining's ore sorting technology to reignite the Mt Todd gold project, in the Northern Territory of Australia. Mt Todd, which was acquired in 2006, hosts one of the country's biggest undeveloped gold resources. A recently completed prefeasibility study outlined a 50,000 t/d operation producing 413,400 ...
The mining energy value chain starts at the face and extends to smelting and refining. System designs that conserve energy and apply energy-efficient technologies can result in significant reductions in overall energy usage. A main component of the energy value chain involves comminution, which accounts for about 50% of all energy used by …
Previously, the comminution results of Tower Mill and IsaMill were compared [3, 14,15]. Since IsaMills are operated at higher tip speed with lower media size, it was named as energy-efficient ...
Having developed a good relationship with our regional team, Ivrindi Gold decided to place their trust in FL. It may have seemed quite the leap of faith: the biggest HPGR ever built for a gold heap leach operation; the first F-Series HPGR we had ever built, and the only HPGR operating in hard rock mining in the region.
Outotec's HRC with flanges has been proven to enhance HPGR circuit operation with overall finer product size gradation and the resulting reduction of circulating loads and energy consumption. The flanges enhance the draw-in of material into the roll gap, resulting in a wider operating gap, reducing specific energy consumption and …
