Abstract: |
The process to recover rhodium from rhodium-bearing solution by DETA precipitation method was studied. Rhodium precipitation is in a steady state when reaction temperature is 100 ℃ and dosage of DETA solution is 200 mL for 1 500 mL rhodium-bearing solution. Rhodium powder with purity of 99.9% above is obtained with rhodium direct recovery of 96.77% after calcining and reduction. |
