ABSTRACT

The present review is focused on technological processes used in the industrial practice of molybdenum production from raw materials, i.e. on pyro-metallurgical (oxidative roasting) and hydrometallurgical methods. It was shown that the hydrometallurgical methods have the advantages over the pyro-metallurgical ones: ecological safety and opportunities for production of pure molybdenum salts owing to sorption on acrylic and styrene macroporous anion exchangers with long-chained cross-linking agents.


Keywords: molybdenum; hydro-metallurgical processes; sorption technology; macroporous anion exchangers; long-chained cross-linking agents
