The two varieties of iron ore of India having high iron content are magnetite and hematite. Magnetite is the finest quality iron ore with very high iron content upto 70 per cent. Hematite has an iron content of 50 to 60 per cent but is the most important industrial iron ore in terms of the quantity used.

Three oxygen compounds of iron are known: ferrous oxide, FeO; ferric oxide, Fe2O3; and ferrosoferric oxide, or ferroferric oxide, Fe3O4, which contains iron in both +2 and +3 oxidation states. Ferrous oxide is a greenish to black powder used primarily as a pigment for glasses.

Iron ore looks totally different from the pure iron. There are many iron ores underneath the earth; they are called as limonite, hematite, magnetite and siderite. Iron ores contain few other elements along with iron but in smaller quantities. ... Iron is found in the crust of earth and it is found abundantly.

Note that the front number "2Fe" and "3CO" represents the number of molecules used as mole ratio. The mole ratio between Fe:CO is 2:3. If 2 moles of iron (Fe) gives you 3 moles of carbon monoxide (CO), then 2.003577818 moles of 2Fe must give you: [2.003577818 moles ÷ 2, then × 3] = 3.0053667263 moles of CO.
