Introduction to Mineral Processing or Beneficiation
The products from AG or SAG mills typically feed secondary grinding mills with particles that range in size from 5 cm down to below 100 microns (0.1 mm). The final particle size is determined by downstream processing requirements. Grinding is carried out as a wet process with water content between 50 – 70% by weight.
