The development of the IsaMill was driven by MIM Holdings’ desire to develop its McArthur River lead–zinc deposit in Australia's Northern Territory, and by the need for finer grinding at its Mount Isa lead–zinc concentrator. The mineral grains in the McArthur River deposit were much finer than those of operating mines. Test work had shown that it would be necessary to grind par

In short, IsaMill™ reduces the energy cost, media cost and capital cost of fine-grinding. The IsaMill™ is used extensively in base metals, PGM, gold processing and magnetite grinding applications. And the power capacity of an IsaMill™ ranges from 75kW to 3.8mW. IsaMill™ is the real-world specification of choice in: mainstream grinding
MoreThe new generation of stirred mills like the IsaMill has fundamentally changed the economics of fine grinding. This has made them enabling technology for several existing and planned operations, and has opened new fields of processing in hydrometallurgy. These opportunities are made possible by the unique combination of features of stirred mills : • Very high intensity
Morefine grinding bench scale mills, leaching copper sulphide concentrate using the Albion process (Clark and Burford, 2004). While all fine grinding methods produced a similar P 80, the IsaMillTM produced the finest P 98. This P 98 /P 80 ratio is an excellent indication of how sharp the feed sizing is, i.e. the closer to
