Iron Ore | HowStuffWorks
Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron …

Iron I
Some barren waste! Iron ore is Michigan's most valuable non-fuel, mined commodity. In 1994, the Lake Superior area produced 95% of the US's supply of iron ore. Minnesota leads the nation with 70% of the production, while Michigan produces most of the rest (25%). More than 98% of the iron ore that is shipped in the world is used to make ...
Direct reduced iron process
In contrast to the blast furnace process, the direct-reduced iron process operates at temperatures of up to 1000 °C. The iron ores are therefore not melted! This also applies to the gangue contained in the ore, which is why the iron ores used must be relatively low in gangue from the outset. The reduction gases only dissolve oxygen from …

8.2. Iron ore crushing and screening. Iron ore is one of the main raw materials to make steel. About 98% of the mined iron ore is used to make steel either by the blast furnace—basic oxygen furnace (BF-BOF) route or through the electrical arc furnace (EAF) route. The majority of world crude steel is made from the BF-BOF route.

Direct Reduction Ironmaking. It is the non-coke ironmaking process in which a gaseous, liquid, or solid reductant is used to reduce the iron ore into metallic iron in a temperature less than the ore softening temperature. The product is direct reduction iron which is an ideal raw material for producing high-quality steel and clean steel.
