The average large South African gold mine hoists in the order of Mt of rock annually comprising about Mt of ore and approximately Mt (20 per cent) waste. Key data from Anglogold (2001) suggest an average shaft overcapacity of 17% in respect of rock hoisted and an average mill overcapacity of 42%, in respect of ore hoisted for

 · In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner .

 ·  · In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
