The eastern region itself accounts for the 55% of the total Iron ore of our country. The share of lumps in total iron ore production has been about 40 % with the rest being accounted for fines and concentrates. Iron Ore Fines/blue dust cannot be charged in the blast furnace directly since they block the passage for ascending gas inside the feed.
An iron ore mine prepares pre-crusher stockpiles, feeding the processing plant with ore at target composition, in grade (iron and multiple contaminants) and physical and source characteristics. Weekly, ore blocks to be mined are allocated to the previous stockpile, or to a new stockpile. By week end, the previous stockpile is completed.
Therefore, the TI of iron-bearing materials should be > 95% + 6.3 mm and the RDI < 12% − 6.3 mm, as well as CCS > 225 kg. More fines in the shaft furnace decrease the bed permeability, leading to nonuniform gas flow and temperatures in the shaft as well as difficulties in injecting the reducing gas through the bustle.
