  • Gold Mining Process Development Denver Mineral Engineers

    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.
