copper and molybdenum process

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.

Process for recovering copper and molybdenum from

Low grade copper concentrates containing molybdenum are roasted under conditions to form copper and molybdenum compounds which are soluble in dilute sulfuric acid solutions. Molybdenum is then recovered by solvent extraction from these solutions and further precipitated as ammonium molybdate, while copper can be electrowinned or precipitated from the raffinate.

Molybdenum processing Britannica

2020-8-17  Molybdenum and copper-molybdenum porphyries are mined by open-pit or by underground methods. Once the ore has been crushed and ground, the metallic minerals are then separated from gangue minerals (or the molybdenum and copper from each other) by flotation processes, using a wide variety of reagents.

How Is Molybdenum Mined and Processed?

2019-9-5  Molybdenum exists in many minerals, but only molybdenite (MoS2) is suitable for the industrial production of molybdenum products. Molybdenite may be the only mineralized mineral in a single ore body, but it usually co-exists with other metals, especially copper sulfide minerals. The molybdenum content of each ore body is between 0.01 and 0.25%.
