  • NATURAL RESOURCES SUSTAINABILITY: IRON ORE MINING .

    The chemical composition and iron grade must be determined to modify the blast furnace energy demand (approximately 1–2 GJ/t) [4]. The energy needs of a blast furnace depend on the quality of the ore. As the metal content increases, the energy required for the production of iron decreases. A lower metal content results in more slag, as well as greater limestone additions .
