US4329168A - Amine treatment for passivating sponge iron ...

Sponge iron 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 sponge iron to a safe temperature.

Extractive Metallurgy: Sponge Iron Making

Oct 11, 2013  The process of sponge iron manufacturing involves removal of oxygen from iron ore. When that happens, the departing oxygen causes micro pores in the ore body, turning it porous. When the eventual product is observed under a microscope, it resembles a honeycomb structure, which looks spongy in texture. Hence the name sponge iron.
