DRI Plant

Direct Reduced is a basic raw material for electric steelmaking plants

The major raw materials required for the production of DRI are iron oxides in form of lump iron ore / pellets, non-coking coal and fluxes (limestone and dolomite) which are sourced from mines in Jharkhand and Orissa. AIPPL has firmly tied up with the source of essential raw materials to maintain viability and sustaining prowess in the project.

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 AIPPL is as shown below:
