ABSTRACT:
In the fluidized bed chlorination of oxidic materials, for example minerals such as bauxite, tantalite, columbite, wolframite or scheelite, the separation of metal values giving vaporous chlorides at the reaction temperature is enhanced by maintaining a zone substantially free of chlorine in the fluidized bed, for example a zone at least 0.25 m in depth measured from the expanded bed surface. A high aspect ratio bed and counter current movement of the bed matter and the chlorine within the bed are preferably used.
