| description | The invention relates to a technique for enriching and recovering indium and associated copper from a low-concentration indium-containing solution. The low-concentration indium-containing solution is a zinc oxide low immersion liquid which mainly contains 200-300 mg/L In, 100-150 g/L Zn, 10-30 g/L H2SO4, trace-3.5 g/L Cu, 5-15 g/L total Fe, trace-8 g/L Fe and 0.8-2.5 As . The technique comprises the following steps: adding a copper-containing solution into the low-concentration indium-containing solution to obtain a mixed solution, wherein the copper-containing solution is a lead zinc smelting production solution and mainly contains 5-35 g/L Cu, trace-10 g/L Cd, 25-35 g/L H2SO4 and 5-10 g/L Fe; adding zinc scum into the mixed solution to carry out neutralization reaction, wherein the zinc scum is mainly composed of 75-85% of ZnO, 15-25% of Zn gold, 0.8-4.5% of Cl and 1-2% of S; and controlling the pH value of the neutralization reaction end point at 4-6, hydrolyzing until the p |
