duty. In the iron ore industry, most of the machines are found in pellet feed applications. How-ever, there are a few notable examples where HPGRs are used for coarse iron ore grinding – in Chile, Mauritania and the USA. The first large scale attempt at applying HPGRs to harder and more abrasive copper and gold ores was in 1996 at Sierrita.
