Issues of gold extraction using cyanide: Cyanide is toxic to animal and plant life and may cause death if exposed to high enough doses. Free cyanide is cyanide ion (CN) and hydrogen cyanide (HCN) which is often gaseous as it is volatile. Free cyanide causes cellular asphyxiation. The process: The ore is ground and crushed to make a slurry
Jul 03, 2015· Of those methods, the ''Cyanide Leaching Process'' (Cyanidation), is the method that is commonly used the most often to do this. As the name implies, the main component in the process is a sodium cyanide solution. This article will give a general overview about how this important, 120 year old gold mining process works.
Cyanide has been the most widely used process for the extraction of gold from its ores for the past 120 years; however, the use of cyanide is under increasing pressure due to its toxicity and consequent deleterious effects on the environment in the event of an unforeseen spill or tailings dam breach.
Cyanide, mercuryfree gold process a reality FIRST gold has been produced using a nontoxic chemical process designed to provide an alternative to using cyanide and mercury to extract the yellow metal.
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 complex. It is the most commonly used leaching process for gold extraction.

Cyanide gas is most dangerous in enclosed places where the gas will be trapped. Cyanide gas evaporates and disperses quickly in open spaces, making it less harmful outdoors. Cyanide gas is less dense than air; so it will rise. Cyanide prevents the cells of the body from using oxygen. When this happens, the cells die.
Together with its historic use up to 1952, the Waihi mining operations have used cyanide since modern operations began in 1988. A substantial database spanning more than 20 years of modern use demonstrates that cyanide can be transported, stored, used and disposed of in a safe manner, with no significant adverse effects on the environment.
RELEVANCE: This chapter is applicable to operating companies that own, control or operate mining projects associated with the production, storage, use or transportation of cyanide; and to any mining project that requires the storage onsite of cyanide in bags or bulk containers, or that use cyanide in a mill process. It applies during
