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. Cyanide leaching is frequently used in conjunction with flotation.
