Extraction of Gold by Flotation Process cnlitereagent. Gold is an easy-floating mineral, so extraction of gold by flotation process has always been one of the effective ways to process gold-bearing ores. In primary gold deposits, gold minerals often coexist with sulfide minerals such as pyrite, chalcopyrite, galena, and sphalerite.

The Process of Froth Flotation The froth flotation method used in the gold mining mainly includes: After washing and classifying, the mineral is mixed evenly by agitation tank drum and sent to the flotation machine. The goldmine generally uses sodium carbonate as the regulator, so that the gold is floated.

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
