What is Concentration of Ore? Definition and Methods

The concentration of Ore can define as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore for the extraction of metal. In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix are the valueless substances that are of
