With the reusing of galvanized scraps in the converter steelmaking process, zinc content in converter sludge increases gradually. The contents of Fe and Zn in Zinc-containing converter sludge are 48.77% and 3.65% respectively. In this study, the hydrometallurgical process of converter sludge in sulfuric acid solutions under atmospheric pressure is investigated in laboratory scale. Leaching behaviors and a sequence of elements from converter sludge were studied. The differences in leaching sequence, metal separation could be achieved by selective leaching.
