| Abstract: |
| The effects of process factors on leaching of lanthanum from red mud with hydrochloric acid were investigated by means of orthogonal experiment. The results show that the leaching rate of lanthanum is 96.67% under the optimum conditions including temperature of 109 ℃ (the boiling point of solution), time of 180 min, concentration of hydrochloric acid of 8 mol/L, and ratio of liquid to solid of 8. |
