This book provides a fascinating study of the very important emerging field of direct reduction in which ore is ‘directly reduced’ in the solid-state, using either natural gas or non-coking coal, to produce a highly metallised material, referred to as or direct reduced . This intermediate product is subsequently melted in electric arc furnaces or induction furnaces

and are the prime raw materials for the production of sponge iron through. The process of sponge iron making aims to remove oxygen from PELLET. When that occurs, the departing oxygen causes micro pores in the ore body making it porous. Yes, I am interested!

may be passivated against reoxidation by air and water vapor by contacting it with an amine containing from about one to about twelve carbon atoms. The amine contact may be accomplished in the vapor phase by adding the amine to a cooling gas which is employed to cool freshly reduced to a safe temperature
