| 摘 要： | 江西铜业集团公司贵溪冶炼厂近年来通过技术改造,形成了30万t/a的矿铜生产能力。贵冶的闪速 炉渣处理方式为电炉贫化,电炉弃渣中含有部分铜,在国内铜精矿资源缺口日益严重的情况下,从电炉弃渣中回收 铜可提高资源综合利用率。江铜贵冶通过借鉴国外成熟的闪速炉渣选矿法及缓冷电炉渣的浮选试验,最终确定使 用电炉渣和转炉渣混选工艺流程回收电炉渣中的铜,该项目投产后每年可从废弃的电炉渣中回收5000t铜金属。

| Abstract: | Through modification expansions in recent years, a annual capacity of 300,000 tons copper is formed in Jiangxi Copper Corporation Guixi Smelter. Slag containing copper out from flash fumace is diluted through electric furnace. With increasingly deficit of domestic copper concentrate supply, recovering copper from slag helps improving comprehensive utilization of resource. Referenced from overseas sophisticated slag cleaning process and floatation tests in Guixi smelter a mixed slag floatation process is finalized for copper recovery form electric furnace, with a target of copper recovered at 5,000 tons per year upon the commissioning of the project. |
