电解锰阳极泥的利用研究进展

Advances in research and utilization of electrolytic manganese anode slime

在电解金属锰的生产过程中不可避免的会产生高含锰率的阳极泥,因其组成和结构较为复杂,大部分阳极泥被作为危险废物堆存或廉价销售,并未得到合理利用.结合近年的文献资料,分析了阳极泥的元素组成、含量及其赋存形态,指出了以还原法、活化法及物理法实现阳极泥资源化存在二次环境污染、电池材料电化学性能差等缺点,明确了以深入分析阳极泥中杂质元素的净化机理为研究方向,提出了以阳极泥为锰源制备锰酸锂电池材料是实现阳极泥资源化的有效途径.

The anode slimes with high rate of manganese were produced in the process of electrolytic manganese metal production. They were piled up as hazardous waste and sold with low price because of their complicated composition and structure, thus they were not reasonably used. Based on the references in recent years, we analyzed the elemental composition, content and speciation of anode slime, and pointed out the disadvantages of resource utilization of anode slim by reduction, activation and physical method, such as secondary environmental pollution and poor electrochemical performance of battery material. Finally, we propose the research direction of the purification mechanism of impurity elements in the anode slime and the efficient way of preparing lithium manganese battery material with anode slime.
