  • Molybdenum Ore Processing by Flotation

    2016-5-5  It resorts entirely to reagent control and flotation to separate the molybdenite from a copper sulphide flotation concentrate. No heat treatment, steaming or roasting steps are used. In this process sodium ferrocyanide and sodium cyanide are used as copper mineral depressants while sulphuric acid is the pH modifier. Copper-Molybdenite Flotation—The low grade ore, after grinding in the conventional manner, is treated by bulk or selective flotation.

    2016-4-19  Copper and molybdenum flotation process is commonly used for copper and molybdenum ore with pretty high grade, while it’s rarely adopted in industrial production. In part combined flotation process, molybdenum with high floatability will be concentrated first, and then copper and molybdenum combined concentrate are concentrated together. Copper and molybdenum will be separated at the

    Re-grinding in the flotation circuit, is the major reason for the loss of molybdenite into the flotation tailing. Abstract The Sungun copper-molybdenum operation in Iran uses a typical copper-molybdenum flowsheet to produce separate copper and molybdenum concentrates through flotation and regrinding of the rougher concentrates arising from the primary circuit.
