Abstract
A method of using coal for reducing iron ore in a fluidized bed to obtain a reduced iron comprising fluidizing and pylolysis of a fine coal in a first fluidized bed, fluidized and thermal cracking the vapored material from the first fluidized bed in a second fluidized bed to deposit carbon on the surface of iron ore particles, fluidizing and reducing the iron ore in a third fluidized bed using reducing gas from generator.
