The different types of iron ore such as haematite and magnetite, limonite and siderite show the variety of iron ores in terms of composition, characteristics, and applications. The nature of each type determines its application, and therefore it is important to understand the characteristics of these ores for effective extraction and use of iron.

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. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content.

Mining (extraction), beneficiation, and processing of iron ore produces iron and steel. Mining is defined as removing ore material from a deposit and encompasses all activities prior to beneficiation. High grade iron ores (iron content greater than 62 %) are simply crushed, screened and shipped directly to the iron making unit (e.g. blast furnace).
