The process may involve the use of molten sodiumcyanide mixtures; pack carburizing with activated solid material such as charcoal or coke, gas or oil carburizing, and dry cyaniding.
The paper introduced the technics process conversion of sodiumcyanide galvanization solution to potassium chloride solution. It expounded in technics, health, entironment, cost, etc.
The drop of global gold price results in the decrease of demand and the fall of price for sodiumcyanide. However, the Chinese high grade flake product is still in demand at some regions.
