Borax method Wikipedia
The borax method is a technique of artisanal gold mining, which uses borax as a flux to purify gold concentrates. By using borax, no mercury flour is produced, hence gold recovery increases. History. The borax method of gold extraction has been used by artisanal gold miners in the Benguet area north of Manila in the Philippines for more than 30 years. Some believe it was in practice as early

Metals Gold Borax
In gold refinement, Dehybor ® anhydrous borax is used in flux formulations to dissolve metal oxides and as a flux in gold assaying. The addition of Dehybor to the smelt is generally 10-50% of total smelt weight, depending on the process. The borax contribution to flux composition can be up to 60% of total flux weight but is typically around 30-40%.
