RECOVERY OF Fe AND Zn FROM FERROUS METALLURGY SOLID WASTE CONTAINING ZINC

According to the fundamental properties of steel making solid wastes，a novel process combining pyrometallurgy and hydrometallurgy technologies was proposed in order to recycle Fe and Zn． And then a series of experiments were carried out to testify its recycling performance． The results showed that this process could not only separate and collect metal such as Fe and Zn，but also made good use of carbon in the solid wastes． In the product，the total iron content could reach 95. 52%，and metallic iron content could reach 94. 81%，thus the recovery rate of iron was up to 91. 53%; the purity of zinc reached 99. 41%，and the recovery of zinc was as high as 93. 82%．
