Method Of Gold Extraction Using Borax Small Scale Miners

Oct 30 2015 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 1025 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 .

Extracting Gold Howstuffworks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill large machines known as crushers reduce the ore to pieces no larger than road gravel.
