Barabil koira Valley in Odisha have the richest iron deposit in India

In India we get four types of iron ores, viz. (a) hematite (Fe203), magnetite (limonite (2Fe203.3H20), and siderite (Fe2C03).

The hematite ore or red-ochre is called 'ox­ide of iron'. It has ferrous content ranging from 60 to 70%. It is mainly found in the Dharwad and Cuddapah rocks of the Peninsular India. It is massive, hard, compact and lumpy ore with reddish or ochre red in colour.

1) types of iron ore :

1, Haematite

2 Magnetite

3 Limonite

4 siderite

2) iron ore distribution in India

2.1) Iron ore in Orissa.

2.2)Iron ore in Chattisgarh

2.3) Iron ore in Jharkhand

2.4) Iron ore in Karnataka

2.5)Iron ore in other states

Haematite

: radish; best quality ; 70% metallic content.

: found in Dharwad and Cuddapah Rock systems of the Peninsular India.

: in the Western section ,

Karnataka Maharashtra and Goa has the this kind of ore.

: magnetic quality

: Dharwad and Cuddapah systems

: Karnataka, Andhra Pradesh ,Rajasthan, Tamilnadu and Kerala.

Lemnonite

:interior of yellowish in colour 42 to 60% iron metal

:the series in Raniganj coalfield in Uttarakhand, Mirzapur in Uttar Pradesh and Kangra valley of Himachal Pradesh.

:advantage =opencast mines = and cheap mining

Sederite

: iron carbonate ;inferior quality less than 40% iron

: contains many impurities { previous post}

mining is not economically variable

: however it is self losing due to presence of lime.
