Process for the extraction of Molybdenum and copper and a purification method of Molybdenum Concentrate contaminated with Copper

摘要

The process of extracting molybdenum and copper includes the first pressure oxidation of molybdenum copper concentrate under oxygen, and the first feeding solution containing copper and halide to produce the first solution containing copper and solid residue containing molybdenum.2. Place the concentrated copper in the second pressure oxidation, oxidize it under oxygen, and use the second feeding solution containing copper and halide to produce the second solution containing copper and solid residues. The second solution containing copper must be extracted by solvent to produce a mother copper solution and a refining process: the first part of the refinery must be recycled to form the second feeding solution of the second oxidation a.Pressure plus first copper solution The second part of the refinery is recovered to form the first feed for pressure oxidation. In addition, the purification method is required for the molybdenum concentrate polluted by copper, including the stage of oxidation of molybdenum concentrate under pressure. Oxygen and energy solutions containing copper and halides
