ABSTRACT:
The process is based on the series of halide-forming affinities. The oxides are passed through a series of zones equal in number to the plurality of halides or mixtures which are to be produced. A halide of an element of lower halide-forming affinity is fed counter-current to the oxides. The halide supply is in stoichiometric equivalent to the total content of halide to be extracted. The oxide of the said fed element is also extracted.
