US4723998A Recovery of gold from carbonaceous ores by

A gold recovery process is disclosed in which the gold content of ores, including carbonaceous ores or mixtures of carbonaceous and oxide ores, is extracted by a simultaneous chlorine leach and ion exchange resin adsorption procedure. The process eliminates or reduces the degree of oxygenation and cyanidation required to conduct a standard gold extraction process.

CN100485059C Method for recovering gold from sulphide

The invention relates to a method for recovering gold from a sulphidic concentrate, particularly one containing arsenopyrite and/or pyrite, hydro- metallurgically. The concentrate is first subjected to leaching with a concentrated solution of alkali chloride and copper (II) chloride, by means of which the copper minerals and some of the gold in the concentrate are made to dissolve.

How to Use Bleach on Gold Ore to Remove Gold Sciencing

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.

Keep Bleach/Chlorine away from Your Gold Jewelry

Both cause a chemical reaction that disintegrates the alloys in the jewelry over time. (Nearly all gold jewelry is alloyed, because pure gold is too soft on its own.) One study showed that when a 14K white gold ring was placed in common household bleach for 36 hours, the ring completely disintegrated! Small amounts of chlorine exist in tap
