    摘要: A process for recovering molybdenum, either as a compound or as the elemental metal, from roasted molybdenum concentrates, e.g. resulting from the roasting of molybdenum sulfide compositions, comprises digesting the concentrate in aqueous nitric acid containing ammonium nitrate, separating the solid phase from the liquid phase, and treating the solid phase with alkali, preferably ammonium hydroxide, to produce ammonium molybdate. The latter may be converted into metallic molybdenum.
