| A New，High_Efficiency and Eco-friendly Short Circuit Copper Production Technology Liang Shuaibiao1; 1CHINA ENFI CORPORATION, Beijing, China; PAPER: 82/Nonferrous/Regular (Oral) SCHEDULED: 12:45/Wed. 30 Nov. 2022/Arcadia 2 ABSTRACT: <p>LI Dong—bo，LIANG Shuai—biao</p> <p>Based on the latest operating practices of copper smelting technology, as well as confronting problems and challenges，a new eco—friendly and short—circuit copper production technology is presented in this thesis. Compared with traditional process of copper pyrometallurgy, smelting-converting-fire refining, the smelting slag is cooled slowly and then mineral processing, the process is long. Three furnaces are used in this process to replace the traditional pyrometallurgical process. The copper smelting furnace, anode—producing furnaces and CR(comprehensive recovery) furnace，which are connected integratedly．It is outstandingly featured with greatly shortened smelting process flow，high comprehensive recovery of valuable metals，high energy efficiency and good environmental performance，which provides a new route for upgrading copper smelting technology．</p> |
