Sodium Cyanide In Gold Mining - Libra-NH
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. Sodium cyanide in gold min.Sodium ferrate was …
Cyanide Use in Gold Mining - Earthworks
How is cyanide used in mining? A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. 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 …
