Magnetic Separation Copper Slag

Apr 01 2019 · An innovative technology for direct reductionmagnetic separation with the addition of Na 2 CO 3 and CaO was studied to upgrade copper slag assaying 4033 Fe total and 065 Cu It is difficult to recover iron and copper from the slag by direct reduction since the iron mainly occurs in fayalite and the copper exists in copper sulfide
