Sponge iron Manufacturing process - Azarbaijan

2021-6-25  The process of making sponge iron occurs by removing oxygen from the iron ore. The quality of sponge iron is mainly determined by the percentage of metallization (removal of oxygen). This parameter is equal to the ratio of metal iron to total iron in the product. Sponge iron itself is not used but can be processed to produce molten iron.
