Sodium Cyanide (NaCN) has been used to recover gold from gold bearing ores. This work aims to develop a simulation model of leaching process by using cyanide solvent for the dissolution of gold...
cyanide (NaCN) are used in gold mining operations, typically in the range of 0.01% to 0.05% cyanide (100 to 500 parts per million [ppm]) for the process of leaching (Logs-don, Hagelstein, & Mudder, 1999). A stable gold-cyanide complex is then formed once the cyanide dissolves the gold from the ore (International Cyanide Management Code
The conventional cyanidation process in gold leaching has been used since 1887. It is currently the main gold leaching process in the world. However, gold cyanidation process has serious environmental risks if an accident occurs in the process because of the toxicity of cyanide.
The first was developed under planetGOLD together with Pact, and addresses best practices in cyanide management for small-scale gold mining. The second, developed by the Global Mercury Partnership and the Minamata Convention Secretariat, provides best practices and recommendations for the management of ASGM tailings, including ways to avoid the ...
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. The two most common …
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. The two most common processes that use cyanide for gold recovery are heap leaching and milling, also known as …

Gold cyanidation, also known as the cyanide process or MacArthur–Forrest process, is a hydrometallurgical method for extracting gold from low-grade ore by converting it into a water-soluble coordination complex. Widely used in gold extraction, cyanidation is also employed in silver extraction after froth flotation.
