CONSUMPTIONS

As compared to other DR process, the DRI and steel production costs through the ENERGIRON Process is lower due to:

  • Lower consumption of iron ore
  • Lower total energy (thermal + electrical) consumption
  • Use of low-cost iron ores

The ENERGIRON process offers the flexibility to operate with low cost oxide pellets or mixtures of oxide pellets and lump ore. There is not a practical limitation regarding the chemical composition of the iron ore.
