Abstract

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.

황동광은 황화계동광 중 가장 풍부하여 구리 확보를 위한 주요한 해외자원개발대상이다. 황동광은 건식제련법에 의하여 처리되어왔으나, SO2 가스 발생 등의 문제가 있어 습식제련법이 연구되어왔다. 이 글에서는 황동광 습식제련법 중 중간생성물을 이용하는 황동광 침출법을 금속을 환원제로 사용하는 방법, 산화환원전위를 조절하는 방법, 배소법, SO2를 이용하는 방법으로 나누어 고찰하고 관련 연구결과들을 정리하였다.
