Introduction to Mineral Processing or Beneficiation

2018-1-12  Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material.

The ore will be sorted after being crushed and the useful minerals and gangue are selected, or the various useful minerals are separated from each other, which is the main part of the beneficiation. The ore dressing methods include magnetic separation, gravity separation, froth flotation, electrification, and chemical separation.
