Iron Ore Pellet
1.1.3.2.1.2 Iron-Bearing Materials. Ore fines and iron concentrates make the main part of the sinter mix. The grain size of ore fines and concentrates is typically 0–8 and 0–3 mm, respectively. Grains smaller than 0.1 mm are not desired because they reduce the gas permeability of the bed and thus decrease the sintering efficiency. Recycled ...
