Dissolve Gold and Silver with Cyanide

2019-8-21 · The addition of gold or silver to an alkaline sodium cyanide solution will cause the gold and silver to react with the cyanide and dissolve into the solution in a process called cyanidation. This process is more frequently referred to as leaching. As well as reacting with the precious metals, the cyanide will react with iron, copper or zinc that may be in the ore.

Silver & Gold Cyanide Leaching of Copper Ore

2019-8-18 · Much work has been done on the effect of copper in cyanide solutions on the leaching of gold. It is generally accepted that copper in cyanide solutions can form complex ions such as Cu(CN)2-, Cu(CN)3=, and Cu(CN)4=-, although Cu(CN)3= is considered the most probable of these. According to leach scientists, the complex having an empirical formula KCu(CN)2, is not a solvent for gold and silver.

Chemical Reaction Related in the Use of Cyanide in

Cyanide in Gold Mining Sodium cyanide is very toxic and an important chemical as it is used to separate the gold and silver particles from the ore. This process was developed in 1887 which helped make mining for gold easier and safer than extracting gold from liquid mercury. Many production companies make a profit of sodium cyanide as it is more expensive and harder to access raw materials.
