Iron Ore | The Canadian Encyclopedia

 · Iron ore usually consists of iron oxides and carbonates. Its most important mineral forms are magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe) and siderite (FeCO 3, 48.29% Fe).

Iron Ore

The raw materials for iron making are (1) iron ore that has been pre-treated by crushing, grinding, washing, sintering, and so on, (2) coke, and (3) limestone, which serves as a flux. Crude iron, called pig iron or cast iron, is produced in a blast furnace–a tower about 100 ft high and 25 ft in diameter that is lined with special refractory (heat-resistant) brick.
