Theory and Practice of Sintering of Iron ore – IspatGuru

On the other hand, the reactivity of iron ore is significantly influenced by its grain size which determines the reaction surface area and packing density (porosity) of the sinter mix. Hence, the particle size of the iron ore is important to control sintering reactions during the sintering process.
