froth flotation process for gold

Gold extraction

Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.

After the flotation begins, an additional amount of the starch depressant can be added based on the color of the froth observed during the flotation process. For example, if the froth becomes black in color then ilmenite and rutile are being pulled into the froth and an additional amount of starch can be added to depress the ilmenite and rutile.
