Cyanide Process Gold Cyanidation Process Gold Leaching

The gold is mixed with the sodium cyanide which leads to the following Elsener’s equation and reaction. This is done to make soluble gold; Now the gold is soluble. This method of making soluble gold is known as leaching. In the process of leaching, a dilute form of sodium cyanide is added into the ore containing the gold.

Gold cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Production of reagentsfor mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide used in other i

An important example is the cyanide complex [Au(CN) 2]-which is one of the compounds involved in the gold extraction process from low grade ores. In addition the Au(-I) oxidation state (electronic confguration d10s2) is known and there are several examples of crystallographically characterised Au(-I) compounds such as [NMe 4 ]Au.

Extracting Gold HowStuffWorks

Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold.
