Gold processing - Refining Britannica

Gold processing - Gold processing - 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 ...

Processing, smelting and refining gold World Gold Council

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.

The process begins when geologists take ore samples to determine the best places for companies to mine. Once mining engineers know where gold is located and what other materials surround it, the mining process can begin. If the gold is located close to the surface, it’s mined with open-pit mining techniques.
