Iron Ore Smelting Process
· The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the …
Materials Production; energy used and carbon emitted
Iron Blast Furnace Materials required: 1. Iron Ore 2. Carbon (coke is used both as fuel and reducing agent). 3. Hot air (hot enough to ensure combustion of the fuel). 4. Flux (removes earthy matter – turns into slag) 5. Slag (combination of calcium carbonate, silica, alumina and other impurities).
Direct reduced iron
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting ...

Smelting area iron/steel
· - Allows for use of stone and steel furnaces (pumping coal/fuel to all of the scattered furnaces would really be a headache) As for the ratio of steel, my factory rarely gets to that point. Because steel absorbs so much valuable iron plate in the early game, I slowly expand my steel production at a rate of one or two furnaces at a time.
Iron and Steel – Analysis
Scrap-based production (also referred to as secondary or recycled production) can be valuable in reducing energy demand and CO 2 emissions, as it is considerably less energy-intensive than primary production from iron ore. Scrap is used as the main ferrous feed in electric arc furnaces (EAFs), as well as in induction furnaces to a lesser extent.
Electric Arc Furnace vs. Blast Furnace | Steel Supply, L.P.
· Uses iron ore as the source of material and coke as the main fuel and sources of energy. Melts iron ore and coke so it can produce pig iron high in carbon content and this is then is fed into a converter to remove impurities. Needs a high investment in facility development and takes up a large space. Easier to produce clean steel.

Iron & steel
· The steel sector is currently highly reliant on coal, which is primarily used to as a reducing agent to extract iron from iron ore and to provide the carbon content needed in steel. While the energy intensity of steel has gradually fallen in the past decade, expanding production has generally raised total energy demand and CO2 emissions.
Improved production of pig iron is effected with lump lignite or sub-bituminous coal that have been heated in hot water or steam under elevated pressure sufficient so that water does not change into steam. High moisture content lignite and sub-bituminous coal, which normally cannot be used in blast furnaces because of slacking, are partially dried by this treatment.
Energy consumption in smelting reduction (SR) processes
In contrast, conventional processes use coke and hematite/sinter in the blast furnace, in SR processes, other alternative fuels and iron ore sources, like charcoal and fine iron ores, can be used to produce sponge iron. The use of these alternative sources, by SR processes, can reduce environmental impacts and lower production costs.
