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, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known

The uses of Iron ore are as follows : About 90 percent of iron ore is used to make steel. Raw iron by itself is not as strong and hard as needed for construction and other purposes. So it is alloyed with other elements to strengthen and harden it, making it useful for construction,automobiles and other forms of transportation such as truck,
The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items.
Iron is an essential mineral which plays a key role in the making of healthy red blood cells. Without healthy red blood cells, your body doesn't get enough oxygen.
Iron farming tools, such as sickles and plough tips, made the process more efficient and allowed farmers to exploit tougher soils, try new crops and have more time for other activities.

Iron also plays a key role in immunity, nerve, and brain function. Have meat, seafood, spinach, and beans to maintain optimum iron levels but don't have more than 18 mg iron a day.
Uses of Hematite (Iron Ore) Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.
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 ore and a good supply of oxygen (provided by a bellows or blower).
The Earth's crust is 5 percent iron, and in some areas, the element concentrates in ores that contain as much as 70 percent iron. When you compare iron and steel with something like aluminum,you can see why it was so important historically.
