Evaluation of the Effect of Sulfur on Iron-Ore .

The vulcanized iron ore could be regenerated with air calcination treatment, and the addition of H2O in the gaseous fuel could prevent the sulfidation of iron ore. The addition of CaO in the oxygen carrier was effective in mitigating the sulfidation and reducing the emission of gaseous sulfur species.
