Abstract
The invention is a method for coproducing Hydrogen and certain metals by reducing a metal oxide(s) with MgH2 or with metal and water, wherein the non-water oxides used in the method include SiO2, Cr2O3, TiO2, SnO2, ZrO2, CuO, ZnO, WO3, Ta2O5, Cs2Cr2O7 or CsOH. The method reacts the MgH2 with a metal oxide or directly uses metal and water instead of a hydride, and initiates a reaction with the metal oxide. The reaction releases Hydrogen and reduces the subject oxide to metal.

A method of co-producing hydrogen and metal comprising the steps of:
- reacting Magnesium hydride and a compound A, selected from a group consisting of metal oxide and metal sulphide, in a fluidized bed reactor wherein a reaction is performed in sealed inert gas flushed reaction chamber and heated between 25° C. and 1000° C.;
- collecting hydrogen gas evolved;
- and
- collecting and separating metal and MgO thus produced.
