Sodium cyanide Podcast Chemistry World

The precious metal dissolves in an aqueous solution of sodium cyanide in the presence of oxygen to form a soluble sodium gold complex. Addition of zinc dust to the solution precipitates the gold out of the complex leaving a sodium zinc cyanide complex and pure gold, which is then processed into an ingot.

Gold cyanidation

Gold cyanidation

Overview

The ore is comminuted using grinding machinery. Depending on the ore, it is sometimes further concentrated by froth flotation or by centrifugal (gravity) concentration. Water is added to produce a slurry or pulp. The basic ore slurry can be combined with a solution of sodium cyanide or potassium cyanide; many operations use calcium cyanide, which is more cost effective.
To prevent the creation of toxic hydrogen cyanide during processing, slaked lime (calcium hydroxide) or

Sodium cyanide

Sodium cyanide

Sodium cyanide is an inorganic compound with the formula Na C N.It is a white, watersoluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals.It is a moderately strong base.When treated with acid, it forms the toxic gas hydrogen cyanide

About Sodium Cyanide. Sodium Cyanide (a.k.a. NaCN) is an inorganic salt, extremely toxic to humans, due to its binding with the Fe3+ ion in the hemoglobin, disabling the use of oxygen by the cells. It is a white cubic crystalline solid also known as white cyanide, and has been the metal cyanide with the greatest commercial importance.

Dissolve Gold and Silver with Cyanide

Dissolve Gold and Silver with Cyanide

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. In order to leach the
