Introduction to Mineral Processing or Beneficiation
Autogenous (AG) and Semi-Autogenous (SAG) milling has seen increased use in recent years, especially in large mineral processing operations. These mills typically have a large diameter relative to their length, typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media.

Final product handling. It normally involves two steps: 1. Dewatering processes, by which the solid particles, either in the concentrate or the tailings streams, are concentrated by elimination of part of the contained water, which is recovered for re-use. This is normally done by using thickeners, although in some cases (concentrates) filters
