Sodium cyanide

Sodium cyanide

Sodium cyanide is an inorganic compound with the formula NaCN. 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 NaCN + H2SO4 HCN + NaHSO4

Bagration states that the solution of metallic gold in cyanide of potassium is facilitated by a rising temperature. Little attention was paid to this point in the early days of the cyanide process, but in 1899 Loewy stated that experiments at the May Consolidated Gold Mine in 1893 yielded 10 to 14 per cent higher extraction when heat was applied.
