The Effect of Increasing Capacity on Gold Recovery and ...
process. Although gold is neutral in oxidation process, but cyanide can be oxidized gold and form a stable and solvable complex ion Au(CN)2. This process takes place in the second stage: In the first stage, liquid oxygen is reduced and formed hydrogen peroxide as an intermediate product and is used for oxidation and production of Au (CN)2

Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination is the most commonly used leaching process for gold extraction..
Mercury and Cyanide Contaminations in Gold Mine ...
Phytoremediation of cyanide contamination was studied by using cyanogenic plants that synthesize cyanogenic glucosides, compounds that readily decompose to cyanide when the plant tissue is injured. Since cyanide is a natural component of these plants, they have enhance capacities for degrading cyanide.
