| Abstract: | According to the characteristics of a molybdenum-lead sulfide ore, a systematic beneficiation-metallurgy experimental study was carried out. By adopting a flowsheet consisting of molybdenum-lead bulk flotation, regrinding of rough concentrate and molybdenum-lead separation, molybdenum concentrate with molybdenum grade and recovery of 52.32% and 88.74%, respectively, can be prepared. After a further intensive beneficiation and chemical leaching to remove impurities, high quality molybdenum concentrate with molybdenum grade and recovery of 57.69% and 58.63%, respectively, was successfully prepared. Therewith technical puzzles of molybdenum-lead separation and impurity reduction for molybdenum concentrate can be solved. |
