Copper and Molybdenum Flotation Process Xinhai

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 last stage. Separation difficulty and process cost of copper and molybdenum is decreased in this process.

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
