The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the .In Platinum ore for example, a specific granulometry is targeted to achieve maximum floatation recovery. If over grind occurs, all the gangue and over-ground chromite float with the mineral which in turn costs the mine millions in smelter penalties.
