摘　　要：含铟粉尘是金属冶炼流程产生的固体废弃物之一,包含锌、钾、铝、铁、铟、铅、镉等金属,是回收稀有金属铟的重要原料。针对现阶段含铟粉尘回收铟过程中存在的分散损失严重、回收率低、处理难度大等问题,本文以含铟粉尘回收铟的全流程处理工艺为主线,对含铟粉尘处理过程中火法预处理、湿法浸出、富集分离等环节的常用技术和工艺进行对比分析,探究不同工艺的独特机理和处理流程,同时讨论不同工艺的特点和局限性,指出现阶段各工序工业生产中存在的问题;重点综述铟湿法浸出和富集分离提取两个环节的技术进展,并基于现阶段工业粉尘“无害化、减量化、资源化”的处理目标与发展趋势,提出未来含铟粉尘综合回收处理的新思路,为实现含铟粉尘中铟等高附加值元素回收利用提供参考。Indium-containing dust is not only one of the solid wastes generated by the metal smelting process,including zinc,potassium,aluminum,iron,indium,lead,cadmium and other metals,but also an important raw material for the recovery of rare metal indium.In view of such problems as serious dispersion loss,low recovery rate and difficult treatment,etc.existing in the process of indium-containing dust recovery of indium at this stage,the whole process of indium-containing dust recovery of indium is taken as the main line,and the common technologies and such processes as fire pretreatment,wet leaching,preconcentration separation,etc.in the process of indium-containing dust treatment are compared and analyzed to explore the unique mechanism and treatment process of different processes,discuss the characteristics and limitations of different processes,and point out the problems existing in the industrial production of each process at this stage.The technical progress of indium wet leaching,preconcentration separation and extraction is reviewed,and based on the treatment goals and development trends of“harmlessness,reduction and recycling”of industrial dust treatment at this stage,a new idea on comprehensive recovery and treatment of indium-containing dust in the future is proposed,which provides references for the recovery of high value-added elements such as indium in indium-containing dust.
