the process of gold ore separation

What are the chemical and physical separation methods used
Physical separation usually involves the difference in mass between gold and most of the other associated minerals. Once the gold is physically separated from the host material and of a relatively similar size it can be separated using a rotary bo

Gold extraction Wikipedia
In 1887, John Stewart MacArthur, working in collaboration with brothers Dr Robert and Dr William Forrest for the Tennant Company in Glasgow, Scotland, developed the MacArthurForrest Process for the extraction of gold ores. By suspending the crushed ore in a cyanide solution, a separation of up to 96 percent pure gold was achieved.

Mercury Usage in Gold Mining and Why It Is a Problem
A mercurygold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. This process does not result in gold that is pure, but it does eliminate the bulk of the impurities.
