  • Iron ore–coal composite pellets/briquettes as new feed

    Around 4 Mt of fine slimes (containing 55 to 60% iron) are generated every year by ore washing plants in India. 4 Mill scales are also the industrial by-product, which are produced due to hot working processes (such as hot rolling, forging and heat treatment of steel etc). At present, most of the slimes and mill scales are thrown away as waste for land filling and create pollution to the environment, which are not desirable.

    It follows from these data that the BREX shows better metallization and reducibility in comparison with the iron ore fines which also means that they will show also better values when compared with the lumpy ore since the reducibility of the iron ore depends strongly on the lump size. 7) The reason for this is evidently related with the presence of the carbon in the BF sludge which promotes for better carbothermic reduction due to the close contact of the iron oxides and the carbon
