The main compound found in haematite is iron(III) oxide, which is chemically represented as Fe₂O₃. Haematite is one of the primary ores of iron and is characterized by its reddish-brown color. It plays a significant role in the production of iron and steel.
Haematite is another name for iron ore. The prefix 'Haem' comes from Classical Greek for iron. Compare with the Latin for iron , which is 'Ferrum' (Fe). Haematite is an oxide of ioron. So by smelting, iron ore was reduced to iron. So the metal in haematite is IRON. Compare with the biological name 'haemaglobin', part of the blood in humans. The 'haem' moiety indicates the 'iron' ion. Or the word ' **Haematuri**a', This is a medical term , for blood in the urine stream.
Iron is bonded to six oxygen ligands.
The main raw material for iron-making is iron ore.There are two iron ore minerals:haematite and magnetite.Actually haematite is an ore where iron is extracted.One can say that haematite is a source if iron.
