While borax appeared to be a viable solution, it can only be used on ore deposits with visible gold, thus confirming poor transferability of the method (Appel and Na-Oy, 2014;Appel and Na-Oy, 2013).

Mercury-Free Gold Extraction Using Borax for Small

2014-6-19  Small-scale gold mining is the largest anthropogenic contributor of mercury pollution on planet Earth. The miners grind gold ore together with mercury in order to recover the fine gold grains. The gold amalgam is burned whereby the mercury evaporates and gold is left behind. This processing extracts only a fraction of the gold in the ore and the released mercury causes serious global health

The Borax Method of Gold Extraction for Small-Scale

16 sacks with 50-kg of ore were randomly taken from several days of gold-ore production. The random selection was used to compensate for the heterogeneity of gold content in the ore. The Kalinga miners processed a sack with their usual amalgamation technique. They recovered 1.2 grams of gold. A second sack was then processed using borax.

How to Use Bleach on Gold Ore to Remove Gold

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.
