Method of Gold Extraction using Borax Small Scale Miners The GravityBorax Method GBM is still unknown to most Artisanal and smallscale gold miners (ASGMs) worldwide as most still use mercury to extract gold. Wholeore amalgamation is a technique that requires the use of 1025 g of mercury to produce 1 g of gold.
If pure gold is required, additional refining steps are necessary to separate out the gold. While this procedure can be used on the very small scale (roughly up to 10 grams) such as in fire assay, its use on a small to medium scale (roughly 100 grams to 10 kg) is not recommended because it emits copious quantities of toxic lead oxide fumes.
#0183;#32;With some borax, heat, and a little knowhow, its possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.
