Composition and structure variations of carbon-coated iron ore during reduction were investigated.
- class="label">•
The Ccritical value of iron ore decreased with the increase of its metallization ratio.
- class="label">•
The Ccritical value reduced to 3.0–3.5 wt.% by process optimization, much lower than the reported value in the literature.
