| Abstract: | The current domestic and foreign research status on the recovery of valuable elements in copper slag and the comprehensive utilization of resources are reviewed. For high-grade iron in copper slag, the advantages and disadvantages of iron resource recovery treatment were discussed and studied mainly from the oxidation roasting magnetic separation method and the direct roasting reduction method. For non-ferrous metals such as cobalt, zinc, copper, gold, silver, and aluminum, the element recovery rate and recovery process were compared. According to the phase composition of the copper slag itself, the application status of the copper slag in the preparation of building materials, glass-ceramics and wastewater treatment was explained. The future application and research direction of copper slag were prospected. |
