| Abstract: | Copper ash from zinc smelting process was used as raw material in the test for leaching of indium-containing copper ash with sulfuric acid, and effects of sulfuric acid concentration, dosage of sulfuric acid, leaching temperature and reaction time, as well as dosage of oxidant (potassium permanganate) on the indium leaching result were all investigated. It is shown that, with sulfuric acid concentration at 300 g/L and liquid-solid ratio at 6 mL/g, a leaching process at the temperature of 90 ℃ for 5 h by adding 0.3% potassium permanganate resulted in the leaching rate of indium from copper ash reaching 65.73%. |
