There are not one but two common processes for refining gold: the Miller process and the Wohlwill process. Other less common methods are cupellation, inquartation and parting, fizzer cell, aqua regia, and the pyrometallurgical process.

The smelting step of refining consists of heating the loaded steel wool to melt the gold at 1300°C, 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 Royal Canadian Mint refines their gold using these five steps: 1. Pre-melt. Doré bars in purities ranging from 5% to 95% are melted in a furnace. Dip samples are taken from the molten gold to determine its purity. 2. Chlorination. Chlorine gas is injected into the molten metal mix. All metals but gold float to the surface to form a slag of ...
