gold at 1300C, with fluxes of silica, feldspar, and borax, to remove impurities. Complete separation occurs within 1.5 hours, at which point the slag is poured off and the molten gold is poured into anode casts and cooled. The anodes are approximately 99% pure and are submerged with 99.9% pure rolled gold cathodes in an electrolytic solution The Borax Method is a technique of artisanal gold mining, with its basis in the principle that borax reduces the melting point of all minerals, including precious metals like gold. The melting point of gold is 1063 C, which is a higher temperature than can be obtained by cheap torches and burners.

The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction. Thus, the bulk of the gold may be recovered by leaching techniques using cyanidation or aqueous chlorination, and the residue may then be treated by smelting to recover the balance.

Mar 01, 2019 This method of gold smelting uses a flux, a substance made of borax and sodium carbonate that removes impurities from gold. The first step is to buy a crucible container, used for holding the gold as it melts. This is a container created specifically for this process as The borax is responsible for separating the gold from its ore and purifying the metal. As all material melt down, they separate from one another. As the process continues, the borax causes the other minerals to oxidize and break down even further. Gold is unaffected by this reaction, it sinks to the bottom of the crucible intact.
