Abstract


The treatment of molybdenite concentrates with nitric acid yields solutions in which copper and iron accompany molybdenum as impurities. The purification of such solutions using the tertiary amine Alamine 336, the quaternary ammonium salt Aliquat 336 or mixtures of both as selective extractants for molybdenum is studied here. Stripping is accomplished with ammonium hydroxide solutions, obtaining ammonium molybdate solutions which can be recirculated to the main circuit for the obtention of ammonium molybdate.
