What is the role of depressant in froth floatation process?

Feb 19, 2019· In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth.

Mineral processing

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

The ore is powdered and a suspension is created in water. The main ingredients of the froth flotation are the Collectors and Froth Stabilizers.

flotation process | Infoplease

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore . Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
