Abstract
The process of selective reduction of iron in ilmenite and the simultaneous formation of Fe–C alloy melting at low temperatures, was investigated. The reduced sample was characterised at each stage using SEM. The influence of temperature, time and additives on the process was studied. It was observed that the size of the alloy particles formed during reduction was strongly influenced by temperature and the morphology of the particles changed significantly with temperature. The size of the particle was ∼150 μm when reduction was carried out at 1673 K. The particles were easily detached from the residual matrix of oxide, at this temperature. The non-magnetic fraction of the reduced samples contained essentially the titanium dioxide.
