How to Use Bleach on Gold Ore to Remove Gold Sciencing

2017-4-24  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.

Bioleaching of Gold Ore Example GraduateWay

2018-2-4  Bioleaching is the process of using certain microbial bacteria in order to liberate a metal from ore. This process has been applied to copper and uranium ore for many years, but has more recently been applied to certain types of gold containing ore. Bioleaching of gold can be performed using a number of different techniques and various microbes
