Flotation
The electrolytic flotation has mainly been used for small plants with capacity between 20 and 30 m 3 h −1. In dissolved air flotation, the bubbles are produced by controlling the pressure of water saturated with air. Three main processes of dissolved air flotation include vacuum flotation, microflotation, and pressurized flotation.

In flotation of gold-containing base metal ores, a number of modifiers normally used for selective flotation of copper lead, lead zinc and copper lead zinc have a negative effect on the floatability of gold. Such modifiers include ZnSO. 4 ·7H. 2. O, SO. 2,Na. 2. S. 2. O. 5. and cyanide when added in excessive amounts.
Electroflotation process: A review
Flotation constitutes a gravity separation process that certainly originated from minerals processing (termed froth flotation). The importance of flotation to economy of the whole industrial world is considered to be enormous. Without this separation process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly.
