摘要
电解锰渣是电解锰生产过程中锰矿石的酸浸废渣,因含锰量低、杂质多,工厂一般采用堆砌填埋的方式处理。随着电解锰行业资源整合和国家出台相关清洁生产标准的提出,锰渣所造成的重金属污染及大量堆存越来越受到人们的重视,对电解锰渣的有效利用已成为科研工作者研究的热点。本文综合了近年来国内利用电解锰废渣在建筑材料方面的各种研究及工业化应用,包括利用电解废锰渣制备免烧砖、烧结砖、保温墙砖等在工业化中的应用,通过工艺介绍和对锰渣含量、产品性能、以及工业化应用前景和瓶颈进行分析,为各科研工作者在电解废锰渣资源化利用提供参考和指导。
Electrolytic manganese slag is the acid leaching residue of manganese ore in the process of electrolytic manganese production. The methods of filling and burying are usually used to deal with the waste which includes low manganese and more impurities by the factory. More and more people attach importance to heavy metal pollution caused by manganese slag and the stockpiling,the effective utilization of electrolytic manganese slag has become a hot topic in scientific research. The study and application of electrolytic manganese slag in building materials are reviewed in this paper, including application of preparation of unburned brick, wall insulation and etc. , which provide reference and guidance for scientific research workers in the utilization of electrolytic manganese slag.
