Ores are the minerals from which metals are conveniently and profitably extracted. Some of the ores of iron are hematite, magnetite, siderite, iron pyrites etc. Moreover, among all the ores of iron, magnetite is the finest quality iron ore. So, now let's discuss the iron ores in detail. First of all, we will discuss the properties of magnetite.

Composition: Hematite consists of iron (Fe) and oxygen (O) atoms, with two iron atoms bonded to three oxygen atoms in each formula unit (Fe2O3). Iron Content: Hematite is a rich source of iron, typically containing about 70% iron by weight. This high iron content makes it an important ore for iron extraction and steel production.
