1. Introduction. Nowadays, with the increasing depletion of high grade and coarse-grained ores, the trend is towards the extraction of low-grade ores .This can have two consequences for the minerals industry; first to process larger tonnages of mineral raw material and second to grind the raw materials to finer sizes, which in turn leads to higher energy consumption.
