Iron is chemically active and forms two major series of chemical compounds, the bivalent iron (II), or ferrous, compounds and the trivalent iron (III), or ferric, compounds. Applications Iron is the most used of all the metals, including 95 % of all the metal tonnage produced worldwide.
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. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

The plentiful iron pyrite, FeS 2 is not an acceptable ore because sulphur is a deleterious impurity in iron, and expensive to remove in refining. Iron is the fourth most plentiful element in the earth's crust (4.6%), but is so widely disseminated that it can be obtained only from ores in which iron has been specially concentrated. Much of this concentration, incidentally, occurred very early ...
The most common iron-containing ore is haematite, but iron is found widely distributed in other minerals such as magnetite and taconite. Commercially, iron is produced in a blast furnace by heating haematite or magnetite with coke (carbon) and limestone (calcium carbonate).
Steel is an alloy of iron and various other metals, which are used to enhance the properties (strength, resistance to corrosion, tolerance of heat etc.) of iron. Changing the type and amount of the elements alloyed with iron can produce different types of steel.

Characteristics: Iron is a ductile, gray, relatively soft metal and is a moderately good conductor of heat and electricity. It is attracted by magnets and can be readily magnetized. The pure metal is chemically very reactive and rusts readily in moist air, forming red-brown oxides. There are three allotropic forms of iron, known as alpha, gamma, and delta. Alpha iron, also known as ferrite, is ...
For example, haematite (from the Greek word meaning 'blood-stone') is a red ore of iron and is responsible for the red colour in our rocks and the deep red sands of the Australian deserts. Some of these rocks are more than 600 million years old! Australia has huge reserves of iron ore (mostly in the Pilbara region of Western Australia) and we supply 1/8th of the world's iron ore needs.
