GOLD AND SILVER

Cyanidation leaching is the primary means of recovery of fine gold and silver. In this process, solutions of sodium or potassium cyanide are brought into contact with an ore which may or may not have required extensive preparation prior to leaching. Gold and silver are dissolved by cyanide in solutions of high pH in the presence of oxygen.

01/01/2018 · Cyanidation, in simple terms, is an electrochemical process that oxidizes gold and reduces oxygen. In addition, it involves the use of different cyanide salts as leaching agents which form gold complexes in the alkaline solution. Many operational conditions influence the cyanidation process,, cyanide concentration, pH, temperature, particle size, and pulp density. However, the most ...

Removal of copper cyanide complexes from solutions formed ...

An innovative process for removing copper cyanide complexes including silver and zinc from cyanidation circuits has been developed. The technology was based on the inducing the nucleated precipitation of copper and silver in a tube serpentine reactor, using sodium sulfide as the precipitate and sulfuric acid as pH control.

Gold_cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthurForrest Process) is a metallurgical technique for extracting gold from lowgrade ore by converting the gold to water soluble aurocyanide metallic complex ions. It is the most commonly used process for gold to the highly poisonous nature of cyanide, the process is highly controversial.
