Material Sciences, Physical Sciences

Focus Area:

Waste Materials Utilisation

Social Benefits:

The process utilises ~100% waste raw materials (iron ore fines, slimes and likewise and coal fines such as middling coal, rejected coal, non coking coal, jhama coal and likewise) generated during mining and processing of raw materials for preparation of blast furnace burden, The DRI produced from this process is highly metallised (Metallisation 96%) with low Sulphur (0.006%S) , Used as substitute of scrap /feed material for induction furnace, electric arc furnace and Basic Oxygen Furnace (BOF) for steelmaking.
