Method for the production of SODIUM SULPHIDE

Sodium sulfide solution refining method to produce a by-product of barium sulfate precipitation concentration of about 4% as raw material, use the pump into the double-effect evaporator concentration to 23%, into the mixing tank iron removal, carbon removal treatment, use the pump into the evaporator ( pure nickel material manufacturing ) evaporation lye to concentration, sent to the machine. Drum water internal cooling type production, after screening, packaging and finished product.

Pulverized coal reduction of mirabilite method this method is the production of sodium sulfide traditional, equipment, material, increase the iron removal process so that products meet the standard improvement in the machining process.
