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.
We are a small mining operation in southern CA. We mine the raw material, crush it, place in a sluice flood with water and when the cyanide is added it causes the gold/silver to float free of the debris. Once we have an adequate amount of gold, sodium nitrate is used to remove the gold.

Dec 31, 2015· What is the Cyanide Gold Mining? Cyanide extraction of gold may be used in areas where fine gold-bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold cyanide or silver cyanide solution. Zinc is added to.

Cyanide is destroyed by sodium thiosulfate or sodium nitrite. An average fatal dose of HCN is about 50-60 milligrams. Cyanide dissolves both gold and silver from alkaline solution. Cyanide is a very “clean” extraction system, as it does not extract many of the base metals such as iron.

Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.
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.
Although “cyanidation”—the use of a sodium cyanide compound to separate a precious metal from finely ground rock—has become less common in other forms of mining, it is still the dominant practice in gold mining. Some 90 percent of gold mines around the …
Sodium cyanide is an inorganic compound with the formula Na C N.It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals.It is a strong base.When treated with acid, it forms the toxic gas hydrogen cyanide:
