Extraction of Gold by Flotation Process

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. These minerals are both easy-floating minerals and form stable mineralized foams. They are the ideal carrier minerals ...

Common Gold Mining Process – Gold Flotation Process-xinhai

The gold flotation process can not only enrich maximum gold into the sulphide mineral concentrate, but also discard the tailings, so the processing cost is low. Besides, the gold flotation process can also be used to polymetallic gold mining, such as gold-copper, gold-lead, gold-antimony, gold-copper-lead-zinc-sulfur ores. For this kind of ores, the gold flotation process can effectively ...

Optimisation of gold recovery by selective gold flotation ...

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides. This may be an alternative treatment route for gold room applications where ...

Gold Mining Process Development – Denver Mineral Engineers

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. Advantages of the flotation process are that gold values are generally ...
