氧化锰矿浸出液净化技术研究进展

A Research Progress on Purification Technology of Leaching Solution from Manganese Oxide Ore

净化是锰冶金过程中重要的环节。硫酸锰溶液既是锰在湿法冶炼过程中的主要载体也是其他锰产品的中间体,其净化的工艺对后续锰产品的质量产生重要影响。以硫酸锰溶液中主要杂质为视角,从铁钾钠、钙镁、钴镉镍、其他金属元素、非金属元素及其化合物等五方面,总结了硫酸锰溶液中杂质的净化技术进展,提出了技术改进的建议,以期为相关工作提供参考。

Purification is the critical process in the manganese metallurgy.Manganese sulfate solution is not only the carrier of manganese,but also the intermediate of later Mn products.Based on the main impurities purification technology on the leaching solution of manganese ore,it is reviewed on iron-potassium-sodium,calcium-magnesium,cobalt-cadmium-nickel,other metals and nonmetallic elements and corresponding compounds.Some relevant suggestions are offered.
