After all, iron ore is a finite natural resource. To combat this problem, manufacturers of steel looked for alternatives that ensured complete utilisation of the ore. Thus, the production of pellets gained momentum. 2. The other obvious reason for a higher demand of Iron Ore Pellets has been the rising demand for steel.

The bonding phases of deposits for fluxed pellets had higher CaO and Fe 2 O 3 contents than acidic iron ore pellets. For the deposit samples from iron ore fluxed pellet production, the area of bonding phases in the phase diagram of CaOAl 2 O 3SiO 25wt%MgO moved to the higher CaO part, which had a lower liquid temperature. The change in the ...
