| Abstract: |
| The development of copper smelting pyrometallurgical process was described in detail. The main links of wastewater produced in copper smelting process were analyzed. The process and principle of wastewater treatment were reviewed. The generation nodes, characteristics and components of wastewater in copper smelting enterprise were analyzed, and reasonable suggestions on the existing wastewater treatment process and wastewater resource utilization were put forward. In particular, the characteristics copper suspension smelting technology, crude copper self oxidation-reduction refining technology, parallel flow electrolysis technology, as well as the combined process of vulcanization + gypsum + neutralization, and advanced wastewater treatment independently developed by Yanggu Xiangguang Copper Co., Ltd, were briefly described, which will be of reference significance for wastewater treatment and resource utilization in copper smelting enterprises using pyrometallurgical process. |
