- W2350909171 abstract "Copper in the chlorination dust of copper-containing slag was recovered through the hydrochloric acid agitation leaching-N902 extraction process, and the main influential factors on the leaching of the chlorination dust were studied. The results show that under the conditions of 15% concentration of hydrochloric acid, ratio of liquid to solid 4 m L/g, reaction temperature 60 ℃ and reaction time 1 h, the leaching rate of copper is 98.95%. Meanwhile, the leaching rates of iron, nickel and zinc are 91.58%, 95.8% and 93.66%, but the leaching rate of lead is low at 5.96%. The leaching process realizes the separation of copper and lead effectively. N902 for copper extraction has good selectivity. When the mixing time, phase ratio, N902 concentration and p H value are 120 s, 1:1, 30% and 3.0 respectively, the copper concentration in the leaching solution decreases from 7.4 to 0.11 g/L, the extraction rate of copper is 98.51%, and the extraction rates of iron, nickel, zinc and lead are all lower than 1.5%." @default.
