| 摘 要： | 电解锰行业每年产生7.5~12万t的锰阳极泥固废, 其矿物组成与结构复杂, 有价金属组分多、含量高, 综合利用难度大, 目前大部分厂家廉价销售或大量堆存, 造成了严重的资源浪费和环境污染。文章分析了阳极泥的产生机理和资源特点, 综述了阳极泥中主要有价战略金属元素Mn、Pb、Sn、Se的分离回收技术, 对比了还原浸出法、焙烧浸出法、碱熔—浸出法等阳极泥处理方法的优缺点, 提出了硫转化综合回收锰铅锡硒新思路, 可为电解锰阳极泥固废的资源化利用提供技术参考。

| Abstract: | 75 000-120 000 tons of electrolytic manganese anode slime (EMAS) are produced in the electrolytic manganese industry every year. The EMAS has high content of strategic metals, complex mineral compositions and complicated structure, and thus the comprehensive utilization is difficult. At present, most manufacturers sell the EMAS cheaply or take the stockpiling disposal, causing serious waste of resources and environmental pollution. This paper analyzed the production mechanism and resource characteristics of the EMAS, and also summarized the separation and recovery technologies of the valuable metals including Mn, Pb, Sn, and Se from the EMAS. The advantages and disadvantages of the reduction leaching method, roasting-leaching method, and alkali melting-leaching method were reviewed and compared. This paper puts forward a novel technique solution for the comprehensive recovery of Mn, Pb, Sn, and Se by sulfur conversion, which can provide technical reference for utilization of EMAS. |
