| Abstract: |
| With the continuous expansion of copper smelting scale, the amount of arsenic-containing intermediate materials produced has increased year by year, and the recycling and harmless utilization of arsenic-containing materials has become one of the important problems to be solved urgently for the sustainable development of copper smelting industry. The sources of arsenic-containing intermediate materials for copper smelting, the present situation of treatment and utilization of arsenic-containing materials at home and abroad were introduced. The shortcomings of hydrometallurgical process, stabilization and solidification were pointed out. The application of pyrometallurgical process classification and resource utilization of arsenic-containing materials was systematically reviewed. The development direction of harmless and resource utilization technology of arsenic-containing materials in the future was put forward. In view of arsenic sulfide slag reduction, the development of mineral phase conversion dehydration reduction and regeneration technology was presented. |
