ABSTRACT:
This invention relates to a process for reducing metal halates to metal halides, the process comprising reacting a metal halate with a reducing agent in an aqueous alkaline reaction medium having a pH above about 7, wherein the amount of reducing agent is sufficient to reduce substantially all of the metal halate to metal halide.
