lead zinc mine grinding mill

IsaMill Wikipedia

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 part of the ore so that 80%

Our process Glencore

Crushing and grinding. The impure zinc-lead ore transported from the mine is ground into a fine dust. Crusher machines break the ore down into nine millimetre rock sizes, then grinding mills further reduce it to 45 microns just big enough for the eye to see. After crushing and grinding, the saleable zinc-lead product is separated from waste rock through a flotation process. The ball mill

TOWER FINE MILLING EXPERIENCE AT MOUNT ISA MINES

The lead-zinc ore from the mine at Mount Isa has become more difficult to treat in recent years. Efforts to restore performance in the Lead-Zinc concentrator led to the doubling of the total grinding capacity. A KW-700F Tower mill was installed in the LGM circuit (Figure 2) during 1991 as a part of this effort. Several projects have been undertaken since then to eliminate the LGM concentrate
