Pressure oxidation process for the production of ...

The molybdenum-loaded organic phase from the solvent extraction process is first scrubbed with an acid solution, e.g. sulfuric acid, to remove any entrained raffinate which contains copper and iron values. The scrubbed organic phase is then contacted with a stripping medium to recover the molybdenum values.
