The Metallurgy of Cyanide Gold Leaching An Introduction. Oct 20, 2014 Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and the gold out of solution resulting in very high loadings on the carbon typically g/t.

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is ... In this form the gold is now soluble. This process is known as leaching. One form of this is heap leaching. In this method dilute sodium cyanide is dripped into ore stacked on an

Cyanide Leaching process is the main method of extracting gold from the ore and the concentrate in modern time. It includes some basic steps, such as cyanide leaching, leaching pulp washing filter, pulp cyanide solution or cyanide gold extraction and smelting of finished products.

Using sodium cyanide solution also eliminates the use of chemicals, such as caustic soda, to maintain a stable pH level when dissolving solid sodium cyanide. Water quality, in particular salinity, can significantly destabilise the pH balance in the dissolution process.

This process of leaching is done in leaching tanks or by heap leaching where sodium cyanide is dripped onto a heap of gold ore and left to percolate its way through the heap of gold ore.

Thus, some alternatives to improve gold dissolution can be suggested: (a) the addition of much more cyanide,, the use of higher concentrated cyanide solutions; (b) to submit the product to some specific treatments that either remove chemical species accounting for degrading cyanide or speeding up their transformation; and (c) use other leaching agents that can be expected to advantageously replace .

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.
