How Cyanide Leaching is Used in Gold Mining - RareGoldNuggets.com

Of those methods the ‘Cyanide Leaching Process’ Cyanidation is the method that is commonly used the most often to do this. As the name implies the main component in the process is a sodium cyanide solution. This article will give a general overview about how this important 120 year old gold mining process works.

Cyanide Use in Gold Mining - Earthworks

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.

Cyanide Leaching Mining SGS

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process a cyanide solution or lixiviant is percolated through ore contained in vats columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.

The thiosulphate leaching of gold ores has great potential to reduce the impact on the environment compared to the cyanidation process. Unlike cyanide which is highly toxic the chemicals used in the thiosulphate leaching

Gold processing - Mining and concentrating Britannica

Gold is then leached from the carbon particles by a strong solution of sodium cyanide and sodium hydroxide and it is recovered from solution by electrowinning directly onto steel wool or by the Merrill-Crowe process. In the latter process the gold-bearing solution is deoxygenated and passed through a filter-press where the gold is displaced

Thiourea leaching of a copper-gold ore showed moderate success Lacoste et al. 1996 .

What is Gold Cyanidation? with picture

Gold cyanidation also called cyanide leaching is a process used to extract gold from ore taken from the ground. It uses cyanide to dissolve the gold within the rock which itself is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.
