  • Gold Extraction & Recovery Processes

    · Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 250 µm This process recovers fine particles of free gold, gold associated in any form with sulphides, and native gold present in polymetallic deposits with certain degree of oxidation For many years, a combination of amalgamation, cyanidation andGold 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 whereOptimisation of gold recovery by selective gold flotation· The common gold extraction processes include gravity separation process, froth flotation process, cyanidation, etc Froth flotation process is the most widely used in gold extraction, but for different types of gold, we can choose flotation process combined processin order to improve the return on investment The combined process between froth flotation process and other processes can4 Types of Gold Ore Froth Flotation Combined Process
