Iron ores occur in igneous, metamorphic transformed, or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite Fe2O3, which is red magnetite Fe3O4, which is black limonite or bog-iron ore 2Fe2O33H2O, which is brown and siderite FeCO3, which is pale brown. Hematite and magnetite are by far the most common types of ore.

China, Brail, Australia, Russia, and Ukraine are the five biggest producers of iron ore, but significant amounts are also mined in India, the United States, Canada, and Kaakhstan. Together, these nine countries produce 80 percent of the worlds iron ore. Brail, Australia, Canada, and India export the most, although Sweden, Liberia, Veneuela, Mauritania, and South Africa also sell large amounts. Japan, the European Union, and the United States are the major importers.

Crushing and screening are straightforward mechanical operations that do not alter an ores composition, but some ores need to be upgraded before smelting. Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.

The upgraded ore, or concentrate, is in the form of a very fine powder that is physically unsuitable for blast furnace use. It has a much smaller particle sie than ore fines and cannot be agglomerated by sintering. Instead, concentrates must be agglomerated by pelletiing, a process that originated in Sweden and Germany about 191213 but was adapted in the 1940s to deal with low-grade taconite ores found in the Mesabi Range of Minnesota, U.S.

First, moistened concentrates are fed to a rotating drum or an inclined disc, the tumbling action of which produces soft, spherical agglomerates. These green balls are then dried and hardened by firing in air to a temperature in the range of 1,250 to 1,340 C 2,300 to 2,440 F. Finally, they are slowly cooled. Finished pellets are round and have diameters of 10 to 15 millimetres, making them almost the ideal shape for the blast furnace.
