Abstract In this study, carbothermal reduction of low grade banded hematite jasper iron ore (Fe~38%) is systematically investigated. The thermodynamic calculations revealed that single phase iron oxide can be reduced to Fe at 700 °C. The thermal pretreatment at 600 °C induced significant random cracks in the underlying matrix. The carbothermal reduction was evaluated .
