Processing, smelting and refining gold World Gold Council
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. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the ...

Gold extraction - Wikipedia
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...

Mining : What Is Gold Mining? How Is Gold Mined?
Placer mining, hard rock mining, byproduct mining and by processing gold ore. Placer mining. Placer mining is the technique of extracting gold accumulated in a placer deposit. Placer deposits are composed of relatively loose material that makes tunneling difficult, so most extraction methods involve water or dredging. Panning. Gold panning is mainly a manual gold separation technique from ...
