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 MacArthur-Forrest 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.

Gold parting - Wikipedia

Separation of gold from silver was not practised in antiquity prior to the Lydian Period (12th century BC to 546BC). Material from Sardis (in modern Turkey) is evidence of the earliest use of gold and silver parting in the 6th century. Literary sources and the lack of physical evidence suggest that gold-silver parting was not practised before the mid first millennium BC.

What are the chemical and physical separation methods

For physical separation method, we usually use gravity separation process. The gravity separation process is a method of deferentially separate ore according to mineral density. So it need not to use chemical. For chemical physical separation method, we usually use flotation process, leaching method to do gold mining. Because in the process, we will use chemical to extract gold from ore. Such as
