  • Recovery of Gold in Pyritic Sulfide Ores Mine Engineer.Com

    Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery.

  • CHLORIDE HYPOCHLORITE OXIDATION AND LEACHING OF

    After 24 hours, direct cyanide leaching of the initial ore resulted in only 54.8% gold recovery. However, cyanidation after dissolving the ore sample in hydrochloric acid (HCl), sulfuric acid (H 2 SO 4), ferric chloride (FeCl 3) and nitric acid (HNO 3), respectively, increased the gold recovery to 98.1%. This shows that the ore is a sulfide refractory gold ore (Saba et al., 2011).

  • Sulphide Gold Ore Treatment by Leaching and Flotation Process

    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.
