After World War II, most of the high grade ore in the United States had been mined out, and so taconite was turned to as a new source of iron. To process taconite, the ore is ground into a fine powder, the iron is separated from the waste rock by using strong magnets, and then the powdered iron concentrate is combined with bentonite clay and limestone as a flux and rolled into pellets about

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

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
