Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)n(H 2 O), 55% Fe) or siderite (FeCO ...

Iron IV - Michigan State University

Basically the taconite process involves crushing the rock to a fine-grain size, then mechanically removing the iron minerals from the waste material. Magnetite can be removed from the siliceous waste materials by large electromagnets. Hematite requires a more sophisticated process for concentration.

The origins of public concern with taconite and

01-10-2008  The difficulties with utilizing taconite as an ore source were many. The fine-grained taconite required extensive grinding to separate the sought-after magnetite (Fe 3 O 4) grains from non-ore or “gangue” minerals.Furthermore, the fine-grained magnetite concentrate that resulted after separation was difficult to ship and use in blast furnaces.
