ABSTRACT:
In the direct reduction of iron ore, there is recovered a solid mixture of carbonaceous reductant and used flux, followed by dispersion of the mixture in an aqueous liquid and carbonation of the flux in the mixture in order to enable effective separation of the used flux from the carbonaceous reductant. After separation, the carbonaceous reductant is recycled to the reducing of iron ore.
