Uses: Potassium cyanide is an important chemical material for heat treatment in ore floatation to extract gold, silver, electroplating and steel. Especially in the field of metal surface electroplating, the potassium cyanide spray possesses the advantages of higher electric current efficiency, broader allowable range of current density and more homogeneous electron-attachment compared with the sodium cyanide spray. Its not only first used in electroplating of noble metals of gold & silver, but also widely used in electroplating of copper & zinc. Its also used as analytical chemical reagent and applied in manufacture of organic nitriles, acrylonitrile & organic glass ,pharmacy, photograph, etching & lithoprint.
