extraction of gold by flotation process

extraction of gold by flotation process

Principle. Gold isan easy-floating mineral, so extraction of gold by flotation process has always been one ofthe 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 for gold …

silver gold recovery flotation process

The ores from which silverand goldare recoverable byflotationdivide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which thegoldand silver are of primary importance, the base-metal minerals, if present, being of little or no value. The first class

optimisation of gold recovery by selective gold flotation

optimisation of gold recovery by selective gold flotation

Abstract. Goldflotation 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
