Iron and Steel Industry The Canadian Encyclopedia

2006-12-14  Iron Ore . After oxygen, silicon and aluminium, iron is the fourth most plentiful element in Earth's crust. It occurs in certain minerals, the most important being magnetite, hematite, goethite, pyrrhotite, siderite, ilmenite and pyrite. The term "iron ore" is used when rock is sufficiently rich in iron minerals to be mined economically.
