摘要： PROBLEM TO BE SOLVED: To provide a method for treating copper-removed slag to facilitate effective utilization of the sulfide-series copper-removed slag. SOLUTION: In the method for treating the copper-removed slag, sulfide-series copper-removed slag containing sodium, iron and sulfur as the main components is treated. The method comprises: a heat-treatment process for heat-treating the copper-removed slag at the temperature of 600-800°C; and a fusible component-separating process for dissolving the fusible components contained in the copper-removed slag after the heat-treatment process into water and separating the fusible components.
