  • Sodium cyanide   </h3>OverviewProduction and chemical propertiesApplicationsToxicitySodium 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

    Gold should be separated from other minerals present in the ore. As gold is insoluble, it should be separated from other minerals to make it soluble. Hence, sodium cyanide can be added, where cyanide ions form a complex ion with the molecules of gold. The cyanide process is as explained below The ore is grounded and crushed.

    Gold is then leached from the carbon particles by a strong solution of sodium cyanide and sodium hydroxide, and it is recovered from solution by electrowinning directly onto steel wool or by the Merrill Crowe process. In the latter process, the gold bearing solution is deoxygenated and passed through a filter press, where the gold is displaced from solution by reduction with zinc metal powder.

    And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal. Chemically, it is a rather simple reaction 4 Au + 8(NaCN) +O2 + 2 H2O = 4 NaAu(CN)2 + 4 NaOH That presumes that the only elements are the gold, Sodium Cyanide and water.
