1.What do you use as RAW Material to do Sodium Sulfide (Na2S) synthesis? the raw material to do sodium sulfide is barite (main content is BaSO4), glauber salt and coal.
The basic process: BaSO4+2C= BaS+2CO2 (high temperature) ,BaS+Na2SO4=BaSO4+Na2S.
2.Where does the iron impurity come from?- The iron impurity mainly come from barite mineral.
