ABSTRACT:
A method and apparatus for producing direct reduced iron from iron oxide fines. The iron oxide raw material is conducted through a series of circulating fluidizable beds in which the fluidizing gas is a strong reducing gas mixture, which allows intimate contact between the fines and the reducing gas to facilitate the direct reduction of the iron oxide fines to metallized iron.
