Sodium cyanide Wikipedia

2020-05-05· 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 moderately strong base.When treated with acid, it forms the toxic gas hydrogen cyanide:

So why was highly toxic cyanide present in the tailings? The answer is gold cyanidation. This process employs sodium cyanide, or sometimes potassium cyanide, to recover gold from low-grade ores. The precious metal dissolves in an aqueous solution of sodium cyanide in the presence of oxygen to form a soluble sodium gold complex. Addition of zinc dust to the solution precipitates the gold out of
