The Borax Method of Gold Extraction for Small-Scale Miners

2012-6-1  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.

Mercury-Free Gold Extraction Using Borax for Small-Scale

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
