Processing, smelting and refining gold | World Gold

The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. 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.

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

Gold | Geoscience Australia

There are both open-cut and underground gold mines in Australia but most of Australia's gold production comes from open-cut mines. Earth-moving equipment is used to remove waste rock from above the ore body and then to mine the ore. Waste and ore are blasted to break them into sizes suitable for handling and transport to waste dumps or, in the case of the ore, to the crusher. Underground

Refining Gold Processing | E & MJ

The processing of refractory gold ores begins with crushing and grinding, followed by flotation at the mine site which reduces the volume of material down to between 2.8% and 4.2% of the original mass by selectively enriching gold mineralization. The resulting concentrate is then transported to the POX Hub by road and/or rail for further processing and gold recovery.
