global sodium cyanide market to be driven by growingjun 07, · the inorganic compound sodium cyanide has the chemical formula nacn. it is a clear, white solid that dissolves in water. since cyanide has a stronger affinity for metals, it has a high toxicity. the products main use is in g mining, which takes advantage of the products high metal reactivity.g mining cyanide extraction of g may be used in areas where fine gbearing rocks are found. sodium cyanide solution is mixed with finely ground rock that is proven to contain g or silver, and is then separated from the ground rock as g cyanide or silver cyanide solution.
