Abstract： Based on the analysis of physicochemical properties of stainless steel EAF dust, the possibility of reducing the impurity (Ca, Mg, O) content in the dust by magnetic separation and reduction process was studied. The results show that the production rate of final magnetic material was 37.39%, total Fe grade up to 53.66%, and the content of main impurities, CaO and MgO, 11.61%, after the treatment of magnetic separation-reduction-magnetic separation. Adding a certain amount of Fe and Cu powder, it could be used as raw material of iron based powder metallurgy friction materials. In comprehensive consideration of production rate of magnetic material, TFe grade and decalcification effect, the suitable magnetic field intensity was in the range of 60~90 mT.
