  • Sulphide Gold Ore Treatment By Leaching And Flotation Process

    Apr 24, 2017 Gold is an almost non reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.The final stage of gold production refining involves removing impurities that remain after the smelting process.Refining companies receive dor bars, as well as scrap gold, and reliquefy the metal in a furnace.

    Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding.This process is repeated to concentrate the gold bearing ore and separate it from the waste rock (increasing the grade of the ore). The flotation units catch 70 of the gold collected at Macraes, with the primary roughers collecting the other 30 .
