| Abstract: |
| The molybdenum in lead concentrate (Mo content of 4.39%) mainly existed in forms of PbMO4. The sodium sulfide leaching process was adopted for oxidation molybdenum extraction. The leaching rate of molybdenum was 85% under the conditions that particle size of ore was 83% -0.0074 mm, the dosage of sodium sulfide was two times as the theoretical value, the ratio of liquid (volume) to solid(mass) was 3∶1, the leaching temperature was 90~95 ℃ and the leaching lasted 1 h. So, Lead was remained in the leaching slag in the form of lead sulfide, and the separation of lead and molybdenum was achieved. |
