ABSTRACT:
A method and apparatus for the continuous production of metals and/or carbides by thermal reduction is described. In the process, a mixture of metal oxide and carbon is agglomerated, each piece of agglomerate encased in carbon and/or graphite, the carbon casing serves as a housing of the agglomerate during the reducing reaction and as an electrical resistance element for heating of the agglomerate, the encased agglomerates are coked and reduced to metal carbide in a tightly-packed form. Extraction of the metal from the carbide is effected with a halide of the same metal.
