With the dust from a tin smelter as raw material, the occurrence state of tin (Sn) and indium (In) therein was firstly studied. Then, a combined processing technique consisting of water leaching and oxidative acid leaching was adopted to separate and recover the key elements of Sn, In, Zn and Cd from the tin smelting dust, and effects of factors including suluric acid concentration, liquid-solid ratio, reaction temperature and reaction time on the leaching process were explored. The results show that Sn and In in the tin smelting dust mainly exist in the forms of SnO₂, In₂S₃ and Zn₂SnO₄. After water leaching treatment, the dust was leached with sulfuric acid at a concentration of 200 g/L by adding potassium permanganate at a dosage of 1.5%, with liquid-solid ratio of 5.0, at a temperature of 65 ℃ for 120 min, resulting in the leaching rates of In, Zn and Cd at 82.00%, 95.60% and 94.30% respectively, while the leaching rate of Sn at 0.84%. After such treatment, the Sn content in the dust increased from 42.44% to 60.87% with an enrichment ratio of 1.43. The particles of the acid leaching residue were porous on the surface, showing that the dust with dense structure changed to the residue with loose one. This tin-rich acid leaching residue with low impurity content can be back to tin smelting process, and indium can go to the subsequent process for extraction and recovery. By this way, efficient recovery and utilization of valuable metals from tin smelting dust can be actualized.

以锡冶炼厂烟尘为原料，对其中Sn、In的赋存形态及分布特性进行研究，采用水浸-氧化酸浸联合工艺分离回收锡冶炼烟尘中的Sn、In、Zn、Cd关键元素，考察了硫酸质量浓度、液固比、浸出温度、浸出时间等因素对浸出效果的影响。结果表明，锡冶炼烟尘中Sn、In主要以SnO₂、In₂S₃和Zn₂SnO₄形式存在。经水浸处理后，在硫酸质量浓度200 g/L、浸出温度65 ℃、浸出时间120 min、浸出液固比5.0、高锰酸钾添加量1.5%条件下氧化酸浸，In、Zn、Cd浸出率分别为82.00%、95.60%、94.30%，Sn浸出率为0.84%；经水浸-氧化酸浸工艺处理后，Sn含量从42.44%提高至60.87%，富集比为1.43。沉淀物酸浸渣颗粒表面呈多孔结构，由烟尘的致密状转变为蓬松状结构，该低杂质含量富锡酸浸渣可返回锡熔炼工序，铟进入萃取回收工序，实现锡冶炼烟尘中有价金属高效回收利用。
