Sodium cyanide is most frequently used in precious metals mining and recovery. NaCN has historically replaced the older method of mining with toxic and stable mercury. Today it is the most gentle chemical substance involved in gold mining. Cyanide compounds in liquid form can extract gold from ore that contains even only a few milligrams.
Draslovka is the world’s largest producer of solid sodium cyanide and our plant in Memphis, Tennessee, which was started in 1952, is the largest solid sodium cyanide plant in the world.
