摘　　要：钙化焙烧-酸浸是一种极具应用前景的清洁提钒工艺,但是所得酸性含钒溶液中锰的含量较高,严重影响钒产品的品质及其应用,因此,对酸性钒溶液中锰的脱除研究亟不可待。对近年来国内外不同溶液体系以及酸性钒溶液中锰的去除进行了综述,阐明了不同溶液锰的去除方法的原理、脱除条件以及除锰效果,并对酸性钒溶液中杂质锰的脱除方法进行了探讨,为高效、高选择性、低成本脱除酸性含钒溶液中的杂质锰提供理论和技术指导。基于酸性含钒溶液体系对除锰剂及除锰方法选择的具体要求,在理论上过硫酸铵氧化法、萃取法和离子交换法适用于该体系中杂质锰的脱除,但具体脱除效果、操作条件和作用机理需进一步研究。Calcification roasting-acid immersion is a very promising clean process for vanadium extraction,but the resultant acidic vanadium solution contains a higher content of manganese,which seriously affects the quality and application of vanadium products.Thus the removal of manganese from the acidic vanadium solution is urgently needed.This paper summarized the removal of manganese from different solution systems at home and abroad.The principles,operational conditions and efficiency of removing manganese from different solutions were expounded and the feasibility for removal of manganese from the acidic vanadium solution via different methods were discussed,which will provide a theoretical and technical guidance for removal of impurity manganese in acidic vanadium solution with high efficiency,high selectivity and low cost.Based on the specific requirements for selecting remover and methods to remove the manganese from the acidic vanadium solution,ammonium persulfate oxidation method,solvent extraction method and ion exchange method are theoretically suitable for removing impurity manganese from this solution system.However,the specific removing efficiency,operational conditions and acting mechanism need to be further studied.
