  • Process for the production of ferrochromium
    Patent number: 4629506
    Abstract: A process for the production of ferrochromium from iron-containing chromium ores, in which the reduction of the ore, which is mixed with coal and slag-forming constituents, is conducted in a rotary kiln at 1480.degree. to 1580.degree. C. in the presence of a CO-containing atmosphere from 20 to 240 minutes, and in which melting follows in a melting furnace at 1600.degree. to 1700.degree. C. By this process, the greatest part of the gangue of the ore can be separated off before melting the reduced ore.
    Type: Grant
