Manganese slag gradient generation and classified resource utilization method
The invention discloses a gradient generation and classified resource utilization method for manganese slag. Belongs to the technical field of industrial waste residue utilization. According to the method, manganese ore is used as a raw material, acid leaching residues, neutralization residues, zinc sulfide and cobalt-nickel-manganese sulfide are generated and separated in an echelon mode in the mode that leaching, neutralization precipitation, step-by-step vulcanization precipitation and filtering operation are alternately used, meanwhile, manganese sulfate purified liquid is obtained, and the acid leaching residues and the neutralization residues are used for preparing calcium sulfate, molecular sieves and cement clinker respectively. According to the method, the manganese slag is generated in a stepped manner, the leachate is purified in a stepped manner, and the problem that different components are difficult to recycle after being mixed is solved. The method is convenient to operate, mild in reaction condition and high in added value of products, and has a good industrial application prospect.
本发明公开了一种锰渣梯级生成与分类资源化利用方法。属于工业废渣利用技术领域。本发明以锰矿石为原料,利用浸出、中和沉淀和分步硫化沉淀与过滤操作交替使用的方式,梯次生成并分离出酸浸渣、中和渣、硫化锌、钴镍锰硫化物,同时得到硫酸锰净化液,并将酸浸渣、中和渣分别用于制备硫酸钙、分子筛和水泥熟料。本发明将锰渣梯级生成、浸出液梯级净化,解决了不同组分混合后难于资源化利用的问题。该法操作方便、反应条件温和、产品附加值高,具有良好的工业应用前景。
