Direct Reduction of Mixtures of Manganese Ore and Iron

It was found that a high metallization degree for Mn can be reached at 1273 K with the reduction of manganese ore by hydrogen-containing gas. Addition of carbon monoxide to the reducing gas retarded the reduction process. The addition of coal to manganese ore and iron ore blends increased the degree of reduction.
