The pyrometallurgical process is characterized in that under the condition of high temperature, carbon is used as a reducing agent to reduce nickel oxide and oxides thereof in nickel oxide ores. At present, 4 kinds of fire process are mainly adopted at home and abroad, including sintering-blast furnace process (BF method); rotary kiln-electric furnace smelting process (RKEF method); a domini eagle bridge shaft furnace-electric furnace process; direct reduction method of rotary kiln in great river mountain of Japan.
