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

Mechanical screening, often just called screening, is the practice of taking granulated or crushed ore material and separating it into multiple grades by particle size. This practice occurs in a variety of industries such as mining and mineral processing , agriculture, pharmaceutical, food, plastics, and recycling.

High-grade hematite ore is referred to as direct shipping ore (DSO) because after it is mined, the ores go through a relatively simple crushing and screening process before being exported for use in steelmaking. Australia''s hematite DSO from the Hamersley region in Western Australia averages from 56% to 62% iron. Like hematite ores, magnetite ores require initial crushing and screening, but

Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, led after World War II 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.

Iron ore has been mined for thousands of years. Iron, the second-most abundant metal on Earth, is the main component of steel. Steel is a strong, valuable building material. Iron is used in everything from glass to fertilizer to the solid-rocket boosters once used for the space shuttle to leave Earth’s atmosphere.
