摘要：
Copper slag is a by-product of pyrometallurgical copper smelting. More than 90% of copper is produced by pyrometallurgical copper smelting. With the progress of science and technology and the needs of people's life, the output of copper in China is increasing year by year. Copper slag contains a lot of recoverable valuable metals, and it is also an excellent inorganic material. The comprehensive recovery of valuable metals in copper slag can reduce the pressure caused by insufficient resources, and the utilization of residual slag can not only reduce environmental pollution, but also produce products with economic value. This paper analyzed and discussed the principle, current situation, advantages and disadvantages of recovering valuable metals from copper slag by means of pyrodilution, wet leaching, beneficiation enrichment and combined process, and summarized the application of copper slag as silicate inorganic materials in building materials and functional materials. The future development direction of metal recovery and resource utilization of copper slag was prospected. © 2021, Chemical Industry Press Co., Ltd. All right reserved.
