摘要: Extracting indium from water quenching slag, which contains poor indium, by two process of leaching, the effect different oxidants and dosages on leaching rate in slag were studied. The conditions: temperature 80 °C, time 2 h, liquid to solid ratio neutral 8︰1, acid 2︰1, initial concentration sulfuric 500 g·L-1, adding oxidants, was detected crystal violet spectrophotometry. Test results showed that significantly improved hydrogen peroxide potassium permanganate. Compared with permanganate higher than indium.
