Integrated Membrane Process Coupled with Metal Sulfide
In gold cyanidation plants, which include a zinc cementation process, there is a progressive increase in zinc content in the solution and a higher cyanide concentration in leaching tailings. Consequently, there are opportunities to: (i) recover zinc and cyanide from these solutions, (ii) generate a saleable ZnS by-product, and (iii) reduce cyanide consumption and …

Advances in the cyanidation of gold
To avoid hydrolysis of cyanide (Eq. (2)), leaching must be carried out under basic conditions: (2) CN − +H 2 O⇒HCN+OH − However, in saline water, such as in many cyanidation plants in Western Australia, gold-leaching is performed at a pH below 10 to reduce the high cost of lime under these buffering conditions. Hydrocyanic acid (HCN) is monitored above the tanks …

The Safe and Effective Use of Cyanide
A process called "Cyanidation", or cyanide leaching, has been the dominant gold extraction technology since the 1970s. In this process sodium cyanide, in a dilute solution of ranging from 100 ppm to 500 ppm or 0.01% to 0.05% cyanide, is used to selectively dissolve gold from ore.

Gold Metallurgy & Leaching in Cyanicides
Cyanidation as applied to ordinary gold and silver ores is a relatively simple process. When cyanicides {cyanide-consuming elements) are encountered in small amounts in the treatment of such ores, the various schemes already discussed, such as use of a lead salt or wasting barren solution, can usually be resorted to and successful operation maintained.

Cyanide Leaching Chemistry & Gold Cyanidation
Therefore, it is practically impossible to predict how an ore will act during cyanidation, although broad generalizations can sometimes be made. In general, therefore, every ore presents its own problems in cyanidation. One of the most frequent sources of trouble, in cyanidation is the presence of copper minerals in an ore.
