BACKGROUND NOTE ON CYANIDE IN GOLD MINING

note on the use of cyanide mining technologies, ahead of the exchange of views with the Commission on 25 September 2013. Cyanide and its environmental and health concerns Cyanide is a chemical group consisting of carbon and nitrogen. Cyanide compounds, such as hydrogen cyanide gas and the simple cyanide salts (sodi um cyanide and potassium

Use of the cyanide Ion Selective Electrode (ISE) for the quantitative deter mination of cyanide in the distillates was investigated during the 1970 period (Frant et al. 1972, Orion Research Inc. 1975, Sekerka and Lechner 1976). Papers were presented before the Division of Environmental Chemistry of the American Chemical Society.

Cyanide Use in Gold Mining Earthworks

Cyanide Use in Gold Mining. What is cyanide? Cyanide is a rapidly acting, potentially deadly chemical. “Cyanide” can mean any one of various compounds containing the chemical group CN: one atom of carbon (C) and one atom of nitrogen (N). Because it is organic, it reacts readily with living organisms.

Use in Mining International Cyanide Management Code

Cyanide is manufactured and distributed for use in the gold and silver mining industries in a variety of physical and chemical forms, including solid briquettes, flake cyanide and liquid cyanide. Sodium cyanide is supplied as either briquettes or liquid, while calcium cyanide is supplied in

Should cyanide still be used in modern-day mining?

According to the ICMC, the amount of cyanide used in commercial gold operations is typically in the range of 0.01% and 0.05% cyanide (100 to 500 parts per million), and the code’s website states that no accidental human deaths due to cyanide poisoning have been documented by the Australian and North American mining industries for over 100 years.

Gold cyanidation Wikipedia

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents
