    Hydrometall urgical Recovery Of Molybdenum From Low …

    The process consists of hydrometallurgical separation of copper and molybdenum from leach solutions of lowgrade molybdenum calcine. The main advantages of the process are increased molybdenum recovery, a less critical roasting of the molybdenite and a high-quality product. Different leaching and separation methods have been studied.
