Oxygen Generation Plant for Gold Leaching PSA (Pressure Swing Adsorption) oxygen generation plant from Noxerior put into operation at the Ad Duwayhi Gold Mine of the Saudi Arabian Mining Company
Gold is an almost nonreactive 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.
