  • Selective Separation Of Gold From Iron Ore Samples Using

    gold in iron ore samples is separated from iron antimony and vanadium using anion exchange resin in hbr, potassium peroxodisulfate and acetone:water:nitric acid media. the exchangeable anion Cl of the ion exchanger dowex cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. cyanide vat leaching mixes finely crushed ore with a cyanide salt in water. the cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.
