the names and formulae of iron ore

The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron.

Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down.

Fe 3 O 4 is the chemical formula of Iron (II, III) oxide which has four oxygen atoms, and three iron atoms. The bond formation between iron and oxygen depends on the difference in electronegativity between them. Iron (Fe) is metal and oxygen (O 2) is non-metal. The bond between them is called an Ionic bond.
