Experience has shown that the best grinding conditions for ores in ball mills are created by a slurry density of between 70% and 80% solids by mass [15,16]. This implies that the milling rates are highest within this range. We investigated the effects of slurry density, grinding time and grinding energy on the grindability of a typical platinum ...
