Today, mine operators in Michigan's Upper Peninsula are generally after taconite, a low-grade ore that was once considered ...
These iron ores have been mined to produce almost every iron and steel object that we use today - from paper clips to automobiles to the steel beams in skyscrapers. How Does Iron Ore Form? Nearly all of Earth's major iron ore deposits are in rocks that formed over 1.8 billion years ago.
The majority of Earth's iron, however, exists in iron ore. Mined right out of the ground, raw ore is mix of ore proper and loose earth called gangue. The ore proper can usually be separated by crushing the raw ore and simply washing away the lighter soil.

Hematite, the most desirable iron ore because of its high iron content, is found throughout the world, with its highest abundance being seen in Australia, Brazil, and parts of Asia. Since the 1960's, high-grade hematite ore has served as the major source of iron mined in Australia. It comprises 96% of the iron ore exports from that continent.
Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.
Today, all of Michigan's iron and steel is produced in the vicinity of Detroit. Three companies operate 8 blast furnaces, having a total rated capacity of 3,769,480 tons of pig iron per year. Michigan's steel capacity is 6th in the nation, rated at 6,769,480 tons per year. Michigan iron ore averages about 51 per cent iron natural.

Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.
Iron ore can be defined on the basis of its iron content into low-grade ore (taconite), which commonly contains 25 to 35% iron, and high-grade ore, which contains 50 to 70% iron. Iron-bearing ore minerals include oxides, carbonates, silicates, and, in some cases, sulfides.
