Refining. Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more readily than gold does at temperatures ...

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 anodes are approximately 99%
