individual sections (the SAG section or ball mill section). As an example, Table 1 presents AG/SAG pilot plant data for an oxide gold ore. Although the overall Wio is close to the BWi, the calculated figures would suggest that the AG/SAG mill is very inefficient, while the ball mill is significantly more efficient than Bond would predict.
The SAG mill at the site grinds the gold ore which is then sent to the autoclave for further processing. The impact of steel balls against ore particles is an efficient grinding method, but it can also wear the liner that protects the cylinder. This can in turn increase maintenance and energy costs.
The IsaMill is an energyefficient 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 applications in the ...
