Sodium Cyanide - Formula, Properties, Uses and Health Effects

The main use of the cyanide is reflected in the process of extraction of gold as well as other precious metals from mines. Gold is highly reactive to cyanide, therefore, sodium cyanide is explicitly used in gold mining. When gold reacts with sodium cyanide in the presence of oxygen and water it produces sodium gold cyanide and sodium hydroxide.

Cyanide Use in Gold Mining - Earthworks

How is cyanide used in mining? A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap.

What is the role of cyanide in mining | MiningFacts

Cyanide, in the form of a very dilute sodium cyanide solution, is used to dissolve and separate gold from ore. [3] The process used to extract gold using cyanide was developed in Scotland in 1887, and was first used in large scale commercial mining by the New Zealand Crown Mines Company at Karangahake in 1889.
