Abstract

Un procédé amélioré de réduction dune composition doxyde métallique mixte doxydes de nickel, de cobalt, de cuivre et de fer dans une atmosphère dhydrogène pour produire un mélange des métaux respectifs, lamélioration dans laquelle latmosphère comprend en outre de la vapeur deau à une concentration, à une température et à un moment pour toucher la réduction sélective des oxydes de cobalt de nickel-cobalt et de cuivre par rapport à loxyde de fer pour produire le mélange métallique avec un taux réduit de fer métallique par rapport aux nickel, cobalt et cuivre métalliques.
