ABSTRACT:
A method of producing direct reduced iron from pellets, lumps and fines of iron oxide. A mixture of iron oxide raw material is introduced to an apparatus which separates the lumps and pellets from the fines. The lumps and pellets are then introduced to a shaft furnace for direct reduction to iron. Fines are conveyed to a series of circulating fluidizable beds which allows intimate contact with reducing gas to facilitate the direct reduction of the iron oxide fines to metallized iron.
