• FROM IRON ORE TO IRON SINTER – PROCESS CONTROL …

    Iron ore sinter materials are an important feedstock material for the steel industry. Since fines cannot be used in conventional blast furnaces because they impair the upward gas flow, they are agglomerated in sinter plants, Gosh & Chatterjee [1]. Most steel plants use coal and iron ores from diverse sites as the major raw material
