Gold Recovery 101 Sepro Mineral Systems

Refractory Gold Any ore that is not readily amenable to recovery by conventional cyanide leaching at a reasonable grind size can be considered refractory. The three primary factors that cause gold ores to be refractory are: Physical encapsulation Extremely fine (<10 µm) particles are locked within an impervious, unreactive mineral.

How to Use Bleach on Gold Ore to Remove Gold Sciencing

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.
