电解锰渣资源化利用研究进展

Advances of Electrolytic Manganese Residue Resource Utilization

电解锰渣是碳酸锰矿经酸浸、氧化沉铁、氨水中和及压滤后产生的酸性废渣。我国大部分企业将废渣筑坝堆存处理,大量锰渣的堆存对环境造成了严重的影响,电解锰渣的利用已成为亟待解决的问题。综合近年来国内外电解锰渣资源化利用的研究,从回收有价金属、制备建筑材料、化肥和吸附材料等方面总结和对比电解锰渣资源化利用的特点,为开发电解锰渣的利用价值提供参考。

Electrolytic manganese residue（EMR） is a kind of acid residue and is produced by acid leaching, iron oxidation, ammonia neutralizing and filtering of manganese carbonate. Most companies stored EMR by stockpiling in China. A large number of stockpiled EMR has caused serious environmental problem. The reuse of EMR has been an immediate problem. This paper summarized the studies of EMR utilization at home and abroad in recent years. Through summarizing and contrasting the characteristics of EMR utilization for recovery of valuable metals from EMR, preparation of construction materials, fertilizer and adsorption materials etc. to provide some valuable references for the further development of EMR utilization.
