Abstract

See full text

There is provided a process of treating a metalliferrous material including at least one metal material fraction. Each one of the at least one metal material fraction includes a respective metal, wherein the respective metal is a transition metal. Each one of the at least one metal material fraction also includes a respective first operative material fraction and a respective second operative material fraction. The respective first operative material fraction consists of an elemental form of the respective metal, and the respective second operative material fraction consists of at least one oxide of the respective metal. The method includes providing reagent material including at least one diatomic halogen and at least one aluminium halide. The reagent material is contacted with the metalliferrous material in a reaction zone so as to effect a reactive process which effects production of an intermediate reaction product including at least one produced metal halide. Each one of the at least one produced metal halide includes a respective metal corresponding to the respective metal of a respective one of the at least one metal material fraction. A separation fraction is separated from the intermediate reaction product. The separation fraction includes at least one recovered metal halide.
