Gold Tailings Reprocessing Technology

There are mainly several methods of gold tailings reprocessing: 1. The iron recovery from gold tailings can adopts common processing technology such as gravity separation, magnetic separation, flotation, roasting magnetic separation and their combined processing technology. There are only four kinds of valuable minerals recovering by magnetic - gravity separation combined technology: magnetite, hematite, ilmenite, and garnet. Among them, the garnet is mainly iron aluminum garnet. 2. Gold

Gold extraction - Wikipedia

Generally, recovery of the gold from the sulfide concentrates requires further processing, usually by roasting or wet pressure oxidation. These pyrometallurgical or hydrometallurgical treatments are themselves usually followed by cyanidation and carbon adsorption techniques for final recovery of the gold.
