Posted on June 01, 2013

Iron ore yields metallic iron (Fe) when heated in the presence of a reducing agent such as coke. Iron ore usually consists of iron oxides and carbonates.

Its most important mineral forms are magnetite (Fe3O4, 72.4% Fe), hematite (Fe2O3, 69.9% Fe) and siderite (FeCO3, 48.29% Fe). In about 1670, deposits of bog iron were found near Trois-Rivières, Qué, and by the 1740s LES FORGES SAINT-MAURICE was producing top-quality cast iron stoves, pots, kettles, bullets and cannons. There are iron ore producers in Newfoundland, Québec and BC.

Canada produces approximately 35 million tonnes of iron ore annually.
