Abstract

PURPOSE: To separate and recover Na, P and V as the forms of the compounds thereof, by treating a desulfurized and dephosphorized slag, e.g. a molten iron prepared with Na2CO3, etc. with water and CO2, and treating the resultant treated slag with Al or Ca ions and NH4 ions, etc.
CONSTITUTION: A slag generated by desulfurizing and dephosphorizing a molten iron or steel with Na2CO3 is wet pulverized to form a slurry, elute and filter off the Na content or Na salts of P and V. The resultant solid material is then treated with water and CO2, and the treated solution is added to the filtrate. CO2 is then blown into the mixture solution to convert the Na content into Na2CO3, and further iron sulfide is then added thereto to precipitate and separate and the S content as FeS. Al2(SO4)3 or CaO is added to precipitate and separate the P content as AlPO4 or Ca3(PO4)2. The residue is then evaporated and concentrated to crystallize and recover the Na2CO3. (NH4)2SO4 is added to the residue to deposit and recover the V content as NH4VO3.
