PROCESS FOR THE PRODUCTION OF FERROCHROMIUM

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 DEG to 1580 DEG C. in the presence of a CO-containing atmosphere from 20 to 240 minutes,...

Beschreibung
Zusammenfassung:	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 DEG to 1580 DEG 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 DEG to 1700 DEG C. By this process, the greatest part of the gangue of the ore can be separated off before melting the reduced ore.
