氧化锰矿还原浸出工艺技术研究进展

摘要

综述了氧化锰矿湿法还原浸出工艺技术的研究进展.分类阐述不同还原剂还原浸出氧化锰矿的浸出过程和反应机理,并总结了浸出过程中所对应的动力学规律.研究表明:湿法还原浸出工艺具有锰浸出率高、环境污染小、浸出成本低等优点.%The technological progress of the reduction leaching process of manganese oxide ore are reviewed in this article. The leaching process and reaction mechanism of reducing manganese oxide ore for different reductant are presented. Meanwhile, the choice of reductant and corresponding reaction kinetics are summarized as well. The results indicate that the hydrometallurgical reducing process of manganese oxide has some advantages, such as high leaching rate,less environmental pollution and low producing cost.
