Dissolve Gold and Silver with Cyanide

As well as reacting with the gold, silver, and other metals in the ore, cyanide will react preferentially with water in an environment of a pH less than about 10, and form Hydrogen Cyanide (HCN), a dangerous and potentially lethal gas.

Gold cyanidationWikipedia

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.

Silver & Gold Cyanide Leaching of Copper Ore

In the silver nitrate titration of cuprocyanides, the silver nitrate reacts with the dissociated CN ions to form the relatively stable sodium silver cyanide. During this reaction, progressively decreasing amounts of CN ions are liberated from the cuprocyanides until equilibrium is established between the cuprocyanides and silver nitrate .

Cyanide Leaching Of GoldMine

It reduces the volume of cyanide required to leach the gold or silver. In addition, hydrogen cyanide is highly toxic to people. So, the few dollars spent on adding a cheap calcium oxide to the ore or solution, prior to leaching is worth the money spent.

Gold Cyanide Method ~ Technology Industry Of Gold Mining

Gold cyanide method is the process of dissolution of gold ore using cyanide chemicals, because every atom of gold requires dissolution of the mineral carrier or impurity with the stoichiometry of two cyanide-soluble compounds.

Use in Mining | International Cyanide Management Code

Cyanide is manufactured and distributed for use in the gold and silver mining industries in a variety of physical and chemical forms, including solid briquettes, flake cyanide and liquid cyanide. Sodium cyanide is supplied as either briquettes or liquid, while calcium cyanide is supplied in flake form and also in liquid form.

The equation is well known, but the successful application of this reaction in a gold mining operation is rarely straightforward. In a typical application, a slurry of the ground ore is mixed with cyanide in the presence of activated carbon.

Chemical Reactions In Mining by Michaela Baker on Prezi

Cyanide is used in the process of separating the gold and silver particles from the ore. These reactions are used to safely (or as safely as possible) remove the particles from the ore. The cyanide mixes with the ground up ore and gold/silver and the cyanide easily reacts and separates the two.
