Risk management approach for cyanides

4.2.1 Metal mining. Sodium cyanide (NaCN; CAS RN 143-33-9) is used mainly as an extraction agent for precious metals (for example, gold, silver) and to a lesser degree for base metals, and as a result, free cyanide and precursors of free cyanide may be released in the effluent of metal mining facilities that use it.

Cyanide Use in Gold Mining

The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.
