| Abstract: |
| Rhodium dissolving process with chloroauric acid was studied. Effects of L/S, gold concentration, hydrochloric acid concentration, reaction temperature, and reaction time on rhodium dissolution rate were investigated. Rhodium dissolution rate is 98.74% under the optimum reaction conditions including L/S=10︰1, gold concentration of 250 g/L, concentration of hydrochloric acid of 11 mol/L, reaction temperature of 130 ℃, reaction time of 18 h, and stirring rate of 50 r/min. |
