Abstract

1,135,848. Reducing iron ores. ESSO RESEARCH & ENG. CO. 26 July, 1966 [2 Sept., 1965], No. 33631/66. Heading C1A. [Also in Division C7] Oxidic Fe ore is fluidized in contact with burning fuel in an oxidizing atmosphere to oxidize any S in the ore or fuel to SO 2 , and then reduced in a series of fluidized beds or zones to Fe 3 O 4 , FeO, and finally Fe. The ore, e.g. haematite, may be ground to 65-325 mesh and fed to the top of a reactor having a series of distinct fluidized beds. Hydrocarbon fuel and excess air are fed to the upper zone, and reducing gases, e.g. H 2 and/or CO, to the remaining zones. A portion of the gases withdrawn from the top reducing zone, e.g. up to 20%, may be burnt with the fuel in the oxidizing zone, and the balance may be treated to remove CO 2 and H 2 O, and then recycled to the bottom reducing zone. Temperatures in the zones may be 1000-1600‹ F. (oxidizing), 1000-1800‹ F. (reducing to Fe 3 O 4 and FeO), and not above 1600‹ F. (reducing to Fe) respectively. The final product contains 85-95% Fe.
