interest in mainstream fine grinding, MIG, and ultra fine grinding of primary flotation concentrates, UFG, is easily illustrated. The tailings' average PGM particle size at an estimated P50 of 5.5 microns illustrates the potential liberation problem if these PGMs are disassociated from sulphides and are associated only with silicates.
velocity of the grinding media along the mill's radius. IV. EQUIPMENT USED A.

Grinding media types Until 2005, all IsaMill installations have taken advantage of the technology's ability to use low cost, but relatively low quality grinding media such as silica sand, river pebble, smelter slag or fine primary mill scats (autogenous milling). Whilst the IsaMill produces high energy efficiencies
To complement the laboratory data on shape, samples were taken from a plant-scale UG2 fine grinding circuit with a ball mill and IsaMill operating in series. This was to determine whether the findings relating to particle shape from the batch laboratory grinding data would be consistent with plant scale operations.
The IsaMill is available in three models (named according to net grinding volume in litres): • M1000 (375 kW) • M3000 (1,120 kW) • M10000 (2,600 kW) IsaMill's are installed in more than two-thirds of the world's ultra fine grinding metalliferous applications. Xstrata Technology directly supports and markets IsaMill technology
The IsaMill is an energy-efficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of the Glencore Xstrata group of companies) and Netzsch Feinmahltechnik ("Netzsch"), a German manufacturer of bead mills.

Tough economical conditions and high grade but fine-grained ore processing have forced the mining industry to look for more efficient processes. IsaMill Technology for ultra-fine and fine grinding is one such process employed at several mining operations in Australia including Mount Isa Mines Limited in Australia. Mount Isa Mines is a business unit of MIM Holdings Limited.

Third, grinding in an inert attritioning environment like an IsaMill increases fine flotation rates by producing clean mineral surfaces. An excellent case study is the installation of IsaMills in the Mount Isa lead zinc concentrator to grind lead and zinc rougher concentrate to P 80 of 12 μm and zinc cleaner tailings to 7 μm.
IsaMill™ Grinding Solutions' performs IsaMill™ testing using a Netzsch LM4 mill, which has the exact same internal dimensions and workings as the IsaMill M4.
