As such, the correct answer is D. Iron metal is usually extracted from a hematite ore, which contains an iron (III) oxide ( ) compound. The ore must be treated before it can be placed in a blast furnace, because blast furnaces are usually optimized to burn small pieces of ore that are compacted together.

As the blast passes through the burning fuel it takes from the oxide of iron its oxygen, passing out as carbonic oxide, and thus compels it to yield up the whole of the metal iron. The iron, as it melts in the furnace, combines with the carbon of the fuel, and becomes cast iron. Although the process involved in refining purifies the iron to a ...

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

Iron, when extracted from iron ore such as haematite containing iron(III) oxide, Fe 2 O 3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron(III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures.

These deposits are commonly referred to as "direct shipping ores" or "natural ores". Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, led after World War II to the development of lowergrade iron ore sources, principally the utilization of magnetite and taconite .

An ore is a type of rock containing compounds from which metals can be extracted. Ores are typically metal oxides or a compound of a metal that can be converted to an oxide. For example, the main aluminium ore is called bauxite which is aluminium oxide (Al 2 O 3). The metal is removed from the oxide in a process called reduction.
