초록
Chalcopyrite (CuFeS2) is most abundant among copper sulfides, and is a main target for oversea resource development to obtain copper. Chalcopyrite has been treated by pyrometallurgical methods, and hydrometallurgical methods for chalcopyrite have been researched because the pyrometallurgical methods have some disadvantages such as SO2 gas emission. In the present article, chalcopyrite indirect leaching methods using intermediate form, which was produced by using metal as a reductant, adjusting an optimum redox potential, roasting, and using SO2 gas were investigated.
