Journal Comment - SciELO

Gravity concentration is by far the oldest form of mineral beneficiation, going back literally thousands of years. As the name implies, this involves the separation of ore minerals from gangue on the basis of density difference. Gravity concentration plays an important role in the processing of diamonds, coal, gold, titanium
