 · Electrolysis is one of the methods used to recover metals with high purity. It is used in metal production from mining and recycling areas. Copper electrolysis, silver electrolysis and gold electrolysis are encountered most frequently in the industry. Unlike refining and leaching methods, it is possible to obtain metal with much higher purity. It is […]

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 …
