Iron Ore

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3),(alt spelling: hematite) goethite, limonite or siderite. Hematite is also known as "natural ore". The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into iron making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel. There are a lot methods of smelting iron ore. The basic principle is to separate iron and oxygen. To do this, usually using carbon. Iron ore mixed with coke and smelt in the furnace. To date, the first smelting of iron ore is China, then followed Brazil and Australia.
