The magnetic product removed by the cobbers may go direct to the ball mill or alterna

Mineral processing - Wikipedia

  

2019-9-30  Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
