Read OnThe LJ ore had a copper content of 0.62%. The main gangue minerals in the LJ ore were quartz, mica, illite, chlorite and calcite. Most of chalcopyrite in the ore was closely associated with pyrite and gangue minerals, occurring mainly in the grain size range of 0.02–0.6 mm.
Read OnGrinding equipment for mineral processing. 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 ...
Read OnThe length and diameter of a SAG mill are determined principally by the desired throughput capacity and the grindability of the ore. For conventional ball mill grinding, grindability is usually expressed in terms of the Bond Work Index, which is determined in laboratory tests and expresses numerically the power required to reduce rock from a ...
