 · Once every mining has exceptional ore properties, the process of dressing plants is a bit different, but substantial parts are unavoidable, such as SAG, ball grinding, and flotations. Depending on the ore exploration method, the dressing process consists .

carried out by size reduction performed by crushers and grinding mills. The ore lumps from the mines have the lump size of 10 100 cm while the individual minerals have grain sizes below mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution.

 · Autogenous grinding is at present carried out in tumbling mills of the same types as used in ball mill grinding. The similarities in equipment and procedure have led to the commonly held assumption that the grinding mechanisms are the same in the two processes, with the coarse part of the ore charge taking over the function of the ball charge.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
