Ore definition is a naturally occurring mineral containing a valuable constituent (such as metal) for which it is mined and worked. a naturally occurring mineral containing a valuable constituent (such as metal) for which it is mined and worked See the full definition.
Increasing iron ore demand, coupled with the depletion of high grade hematite ores in the United States, after World War II led to development of lower grade iron ore sources, principally the utilization of magnetite and taconite. Iron ore mining methods vary by the type of ore being mined.
The world's resources are dominated by low grade ore, though current world production of iron ore is largely by supply from deposits of high grade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil.

173;The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 173;). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.
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). Charcoal is

Sep 23, 20150183;32;Steel is made by adding iron to carbon which hardens the iron. Alloy steel becomes even tougher as other elements like chromium and nickel are introduced. Steel is made by heating and melting iron ore in furnaces. The steel can is tapped from the furnaces and poured into molds to form steel bars.
After the Second World War, declining ore grades and new technologies, including large earth moving machines, spurred the development of opencast mining. These methods, also known as strip mining or open pit mining, remove surface material, or overburden, to reveal extensive, low grade deposits.
The industrial requirements for iron ore quality and properties are diverse. Ores rich in phosphorus (up to 0.30.4 percent) are used to make some types of foundry cast iron. In smelting open hearth cast irons (the main product of blast furnaces) using coke, the sulfur content of the ore introduced into the blast furnace should not exceed 0
