the process of gold ore separation
Gold processing - Refining, Smelting, Purifying Britannica
OverviewRefiningRefining from scrapAssayingThe metal and its alloysChemical compoundsGold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, cThe 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. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride.
