Types of Iron Ore. Based on the amount of ore and iron content, iron ore is classified into various types: Magnetite (FE3O4): It is a good quality ore and has very high iron content (about 70%). Black in colour and has magnetic properties. Haematite (FE2O3): Reddish ore with 60-70% iron. Limonite: Yellowish ore with 40% to 60% iron.

Properties. In the Earth's crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).Iron is quite soft and easily worked, but it has a very high melting point of 1538°C.

Abstract. This chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores. On the other hand, because oxidized …
