Gravity Borax Method GBM Mercury Free Gold Recovery

The Gravity-Borax Method GBM is still unknown to most Artisanal and small-scale gold miners (ASGMs) worldwide as most still use mercury to extract gold. "Whole-ore amalgamation" is a technique that requires the use of 10–25 g of mercury to produce 1 g of gold.Within the last eight years, it has become evident that this technique is more widely used than earlier anticipated, and artisanal ...
