Experimental Studies on Reduction of Coarse Blue …
Huge quantities of Blue dust of various grades is available in the Iron Ore Mines of NMDC Limited. This blue dust as such cannot be used as a feed material for steel production due to its fine nature. This blue dust has to be agglomerated (Sintering and Pelletisation) depending on the size, otherwise this blue dust lies as waste in the mine.
