A new process for producing calcium chloride and other metal halides fr om the carbonates, bicarbonates, oxides of these metals. The process utilizes t he discovery that hydrogen halides, when used in a true or conventional fluidizing medium in shallow beds of the aforementioned solids at moderately elevated temperatures in a continuous counter current process results in the conversi on of the metal carbonates, bicarbonates, and oxides, into metal halides and carbo n dioxide gas and/or water vapor. The process is carried out in a series of tr ue or conventional fluidized beds preferable but not necessarily arranged in a vertical configuration so that the solids flow downward due to the fluidized process and the hydrogen halides flow counter currently in an upward direction producing metal halides at the bottom and pure carbon dioxide gas and/or water vapor a t the top.
