| Abstract: | Oxidation leaching platinum in Spent Catalyst with Hydrogen Peroxide in hydrochloric acid media was researched. The factors in leaching process of leaching temperature, time, solid-liquid ratio and concentration of NaClO3 were discussed with the single-factor test. The results show that leaching rate is 87.43% in conditions of leaching temperature of 90 ℃, leaching time of 3 h, hydrochloric acid solid-liquid ratio of 4：1,2 ml/g HCl of 6 mol/Land 2 ml/g NaClO3 of 0.4 mol/L. |
| Keywords: | platinum spent catalys oxidation leaching organic silicon separation |
