The process of DRI making aims to remove oxygen from iron ore Pellets/ Lumps.
The process of DRI making aims to remove oxygen from iron ore Pellets/ Lumps. When that occurs, the departing oxygen causes micro pores in the ore body making it porous. The final product, when observed under a microscope, resembles a honeycomb structure looking spongy in texture, hence the DRI is also called as SPONGE IRON. The quality of DRI is primarily ascertained by the percentage of metallization (removal of oxygen) , which is the ratio of metallic iron to the total iron present in the product. The metallurgical quality of DRI as to be produced at DRIC is as shown below: Product Cold DRI
