Process for recovering copper and molybdenum from low grade copper concentrates

摘要

Low grade copper concentrates containing molybdenum are roasted under conditions to form copper and molybdenum compounds which are soluble in dilute sulfuric acid solutions.PP 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.PP Overall recovery efficiencies are 96% for copper and 84% for molybdenum.
