PRODUCTION OF METALS ABSTRACT OF THE DISCLOSURE Metals, particularly chromium, are recovered from low grade ore in substantially pure form using non-polluting, procedures. Chromium in the ore is separated from gangue constituents including iron and is formed into sodium chromate. The sodium chromate by solid state reaction is converted to the sponge metal. Metal carbides may be formed by solid state reduction of the corresponding oxides with carbon. |
