Zinc hydrometallurgy extraction of indium
the used more indium in the zinc hydrometallurgy extraction, such as extraction of indium in sulfuric acid medium, can choose P204 extraction agent, the indium extraction solvent extraction technology has been successfully used in industry practice, P204 quantitative extraction of indium in sulphuric acid concentration in a wide range, the extraction rate is correlated with the concentration of sulfuric acid. Practice has proved that using P204 extracting indium, using 0. 56 - 0. 66 mol/L sulfuric acid solution for better bottom liquid, when using P204-30% Kerosene as the organic phase, the triple extraction, extraction of indium can be completed, get loaded organic phase.
