| Abstract: |
| Iron was removed from oxygen pressure sulfuric acid leaching solution of Pt-Pd concentrate by N235 extraction, ferroalumen process, and hematite process respectively. The advantages and disadvantages, cost, and experimental conditions of the three processes were compared. The results show that losses of copper ions and quantity of slag in ferroalumen process and hematite process are both large. Extraction process is worth of further development considering its advantages of small loss of valuable metals and zero-slag produce. |
