IsaMill - Wikipedia

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. The IsaMill is primarily known for its ultrafine grinding …

Energy efficiency • Energy intensity in copper and gold ...

The greatest energy input in copper and gold production is required for the comminution and grinding processes. The energy audit of mainly Australian copper and gold mines shows that 36 % of the overall energy consumption is attributable to comminution [1]. Previous studies had shown values between 18 % and 50 %.
