| Abstract: | A new technology to recover iron from leaching solution of Pt-Pd concentrates of Jinbaoshan ore and to remove sulfuric acid using ion membrane separation technique was studied. The effects of pressure, temperature and reaction time on the iron recovery were investigated, and the process parameters to remove sulfuric acid by ions exchange membrane were also determined. The results indicate that the reagent consumption and the production cost can be reduced with the new process, and the ion oxide red of high purity can be produced |
