Gold extraction by flotation

Flotation process is one of the most widely used methods to process lode gold in gold beneficiation plant. In most instances, flotation process is used for processing sulfide minerals gold ores with high flotability and the effect is most notable. In recent years, the flotation process in gold ores has large evolution. The main performances are innovation process, new drug researching and design improving. Using stage grinding and stage beneficiation process is development trend of gold flotation extraction at present. Many foreign gold beneficiation plants use two stages even three stages and the gold recovery can be improved by 2%-6%. For the flotation process only can enrich the gold into all kinds of sulphur mineral concentrates as much as possible and the final gold products can not be got. Therefore, the beneficiation plants that use single flotation flow are not so much. The flotation process is only used as a process in combination flow.
