Gold processing. Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth's crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in .
The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride.

Precious metal scrap such as placer gold, dental gold scrap and gold metal foil is weighed and then smelted. As the gold scrap liquefies in the furnace, borax and soda ash are mixed in to separate the pure gold from other precious and non-precious metals. A sample is removed for assaying, which is the process of measuring the gold content.
A 1919 trade pamphlet titled "Borax: The Magic Crystal" stated, "Perfect health depends on perfect hygienic cleanliness; and perfect sanitary cleanliness is secured by the use of nature's greatest cleanser and most harmless antiseptic -- Borax."
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 ...

Gold concentrate is combined with a flux, such as borax or other materials of mixtures, in the crucible. The flux acts to decrease the melting temperature and viscosity of non-gold minerals in the concentrate so they are more easily separated from the gold during the cooling process. Small amounts of concentrates, usually around 50 to 100 grams ...
Pour off the slag into a heat resistant container. The liquid will be too thick to pour once it is cold. Add in some borax to thin out the liquid. When the liquid cools, chip off the glass — which will have floated to the top during the cooling process — and there is your gold, smelted to perfection.

borax was derived and borax was perhaps, after all, an artificial product made from it by some secret process in the Far East or one still being guarded by the Dutch refiners2. In February 1779, Paolo Mascagni (1755-1815) discovered solid boric acid (sassolite) at the lagoni of Montecerboli and Castelnuovo. In a paper published
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.
