摘    要:以硫酸为浸出剂,采用氧压浸出的方法进行了含铟锡烟尘提铟试验研究。考察了氧分压、硫酸初始浓度、液固比、浸出温度、浸出时间等因素对铟浸出率的影响,确定了氧压浸出的最佳条件。试验结果表明,含铟物料在液固比4:1,硫酸寝浓度150g/L,温度150℃,压力0.7MPa,时间2.5h的条件下氧压浸出,可获得In93.66%的浸出率。

关 键 词:锡烟尘  硫酸浸出  氧压  浸出率

Abstract:Indium extraction from indium - tin fume experimental investigation is carded out by oxygen pressure leaching method with sulfuric acid as leachant. The optimum condition of oxygen pressure leaching is confirmed through the experiment by investigation of the following factors, which effects indium leaching rate, the factors are : oxygen partial pressure, the initial concentration of sulfuric acid, liquid -solid ratio, leaching temperature, leaching time and so on. The test result shows, the indium leaching rate can be 93.66%, while oxygen pressure leaching is carried out under the following conditions: the liquid-solid ratio is 4: 1, sulfuric acid concentration is 150 g/L, the temperature is 150℃, the pressure is 0. 7 MPa, and the duration time is 2.5 h.
Keywords:tin fume  sulfuric acid leaching  oxygen pressure  leaching rate  indium
