Copper and Molybdenum Flotation Process

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.
