Cupellation (fire assay) is a quantitative analysis technique that is used for determining the amount of precious metals such as gold and silver in ore, concentrate or any other alloy. This process is based on the principle that precious metals do not oxidize or react chemically in high temperatures.

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.

20171012The electrolytic refining process for gold uses hydrochloric acid as the electrolyte. The anode is made of gold alloy and the cathode is usually a thin sheet of high purity gold. The electric current ionises the electrolyte and transfers dissolved gold from the anode to the cathode, thereby increasing the purity of the gold at the cathode.
