Sink Float Separation Process In Ore Dressing

gold

In certain ores, gold and gangue may be separated by flotation. Finely ground ore is placed in a solution of chemicals and water. Some constituents of the ore are wetted by the solution and sink; others are not wetted and float in a froth on top. . The gold yielded by ore-dressing processes remains alloyed with silver and trace

This means of mechanical separation is merely to place finely ground ore containing particles of varying density into a liquid of heavier density than the greater portion of the mineral, which will allow the heavier portions to sink and the lighter to float, which is usually gangue.
