Sulphide Gold Ore Treatment by Leaching and Flotation Process

Apr 18, 2016  For many years, after introduction of the cyanide process for dissolution of gold, the usual practice was to grind all the ore with little or no concentration before cyanidation. There were two general cyanidation flowsheets; sand leaching and all sliming. The latter ultimately has almost completely replaced sand leaching.
