2020-5-21The reagents used for flotation are generally not toxic, which means that tailing 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.

Most methods of water-based gold extraction are dependent on golds lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials which will not mix with water from hydrophilic materials which readily mix with water.
