摘要
综述了电解锰渣资源化与高值化利用的研究进展,重点分析了其在建筑材料(免烧砖、水泥添加剂)、农业肥料、有价元素(锰、氨、氮、硫)回收及高附加值材料(陶瓷、微晶玻璃、分子筛)开发等领域的应用潜力。研究发现,现有技术普遍面临规模化应用受限、二次污染风险、经济性不足及产业化瓶颈等挑战。为此,提出结合高值化与资源化利用思路,实施分质梯级利用策略,建议优先通过湿法浸出回收锰与氨氮,结合高温烧结制备高附加值材料,通过耦合工艺优化与政策引导,实现电解锰渣的无害化处理、全量化消纳与高值化利用。
This paper systematically describes the research progress in the resource utilization and value-added applications of electrolytic manganese residue(EMR),with a focused analysis of its potential applications in building materials(non-fired bricks,cement additives),agricultural fertilizers,recovery of valuable elements(manganese,ammonia nitrogen,sulfur),and development of high value-added materials(ceramics,glass-ceramics,molecular sieves).The study reveals that existing technologies generally face challenges including limitations in large-scale application,secondary pollution risks,insufficient economic viability,and industrialization bottlenecks.To address these issues,the paper propose a graded utilization strategy by means of combining value-added application with resource recovery.It is recommended that priority be given to the recovery of manganese and ammonia nitrogen through hydrometallurgical leaching,combined with high-temperature sintering for producing high value-added materials.This approach advocates integrated process optimization and policy guidance to achieve harmless treatment,complete consumption,and high value-added utilization of EMR.
