ABSTRACT:
This invention provides a process for obtaining substantially pure manganese metal by the reduction of a manganese oxide or a manganese halide by reaction with a subhalide of a transport metal. The transport metal can be aluminum, silicon, or titanium. In preferred embodiments of this procedure, a continuous closed cycle process is carried out wherein the transport metal value is reconverted to its subhalide and recycled for reaction with additional manganese compound.
