extraction of gold with cyanide flowchart

Jan 19 2020 Gold cyanidation also called cyanide leaching is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock which itself is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.

Gold extraction - Wikipedia

John Stewart MacArthur developed the cyanide process for gold extraction in 1887. The solubility of gold in a water and cyanide solution was discovered in 1783 by Carl Wilhelm Scheele, but it was not until the late 19th century, that an industrial process was developed. The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found ...

Extracting Gold HowStuffWorks

2009-02-23  The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon.

Gold mining - Wikipedia

The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning. Gold specific resins can also be used in place of activated carbon, or where selective separation of gold from copper or other dissolved metals is required.
