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 equal to or greater than …

The process of gold assaying is a way to ensure that gold coins or gold bullion bars produced by a gold mint meet the correct purity standards and content. For example, the US Mint guarantees that its American Gold Buffalo Coin has a minimum 99.99% purity. Since the price of gold per ounce is based on 1 troy ounce of per gold, this is important that the assay for 1 ounce coins also measures pure gold

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis
