The processing of smelting iron from its ores was discovered in Asia Minor around 1500 BC. Iron ore from Magnesia in Lydia, Asia Minor, was discovered to attract other pieces of iron; this ore was named "magnetite" and the attractive pieces of metal were named "magnets" after their country of origin.

Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.
