Jan 05 2016 Gold flotation process is one of the most common methods to process gold ore especially for the gold ore with complex components.Preferential adsorption takes place between gold flotation reagents and purpose ore. Gold flotation reagents can be parted into three categories such as collector foamer and regulator.

PDF Gold Extraction and Recovery Processes For Internal

The reagents used for flotation are generally not toxic which means that tailings disposal costs are low. Flotation will frequently be used when gold is recovered in conjunction with other metals such as copper lead or zinc. Flotation concentrates are usually sent to an off-site smelting facility for recovery of gold and base metals.

17 Flotation of Gold Ores

2 17. Flotation of Gold Ores. also for beneficiation and separation of difficult-to-treat refractory gold ores. Flotation is also the best method for recovery of gold from base metal ores and gold-containing PGM ores. Excluding gravity preconcentration flotation remains the most cost-effective bene ficiation method.
