Experimental Investigation of Indium Extraction by Sulfuric Acid Precure Pressure-Atmospheriation Leaching from Tin Dust

Abstract:

Sulfuric Acid precure Pressure-atmospheriation leaching process from tin dust was studied. The factors had been investigated,which effects indium leaching rate,the factors are :the sulfuric acid initial temperature, curing time of heat, acid dosage, leaching reaction time, leaching temperature, the liquid-solid ratio and so on.The results show that the indium, zinc and tin leaching rate can be 96.68%, 97.70% and 0.52%,while pressure-atmospheriation leaching is carried out under the initial temperature 140°C,sulfuric acid, the time of heat aging 40 min, acid dosage and tin of tobacco smoke mass ratio0.7:1, leaching time 1.5h, leaching temperature 90°C,and the liquid-solid ratio 4:1 conditions.
