  • Direct leaching of molybdenum and lead from lean

    01/12/2019· A direct alkaline leaching process was proposed to extract molybdenum and lead from low-grade wulfenite ore containing 2.87% Mo and 9.39% Pb. The results show that increasing temperature and alkali concentration enhances the extraction of Mo and Pb, and more than 99.7% of Mo and 64.6% of Pb are extracted under conditions of 75 °C, L/S of 2:1, leaching time of 1.0 h, initial

  • Process for extracting molybdenum from wulfenite ore

  • Extraction molybdenum

    Molybdenum comes from a sulphide ore called molybdenite. First, the ore must be crushed into a powder and then the copper sulphide must be separated from the rest. What is left is molybdenum sulphide and that is roasted. Now there is molybdenum concentrate and that is then made into molybdenum oxide. After that, the molybdenum oxide "goes through a two-step hydrogen reduction process
