Using Borax Flux to Refine Gold
In metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. With some borax, heat, and a little know-how, it's 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.
Tavener Process
Smelting is performed at similar temperatures to those required for simple flux smelting. The lead oxide is reduced by metals, sulfides, and carbon, if present, to form lead metal. The lead drains through the molten charge as fine droplets and collects the contained gold and silver.
