MINERALS AND INDUSTRIES
MINERALS AND INDUSTRIES
- India is fairly rich in minerals and has sufficiently large reserves of iron ore, coal, manganese, bauxite and Mica. However baring few exceptions, the deposits of nonferrous metals are limited. More than 90% of the mineral deposits of the country are located in the Chhota Nagpur Region. The valleys of the Damodar in the West Bengal and the Jharkhand, the Mahanadi in Chhattisgarh, and Odisha, and the Godavari in Maharashtra and Andhra Pradesh contain practically the entire mineral wealth of the country. Petroleum, copper and gold are the significant mineral deposit outside this area.
- Two distinct belts of mineral deposits can be identified in India. The first lying in Jharkhand, West Bengal and Odisha, yields most of the iron ore, Coal and limestone and a fairly large proportion of the manganese and bauxite. The second extends across Madhya Pradesh, Chhattisgarh, Maharashtra and Andhra Pradesh, and contains large deposits of Mica, Coal, iron, limestone, manganese and other minerals.
CLASSIFICATION AND DISTRIBUTION OF MINERALS
Minerals are classified into metallic and non-metallic forms. Metallic constitutes extracted iron ore, Copper ore, Bauxite. Non-Metallic includes minerals from which metals are not extracted. Mica and limestone are examples. Minerals of Metallic group are further divided into two groups- The ferrous minerals and the non-ferrous minerals. The ferrous minerals have an affinity with iron while the– non-ferrous minerals have no affinity with the iron. Iron, Manganese, nickel is ferrous minerals while Aluminum, Copper, Zinc, Tungsten and lead are non-ferrous minerals. Refractory minerals are the ones which are used as heat resistance in the furnaces etc. Fire clay and Kyanite are the examples of refractory minerals. The minerals which are combustible and are used as fuels are called mineral fuels. Coal, oil and Natural gas are examples of these minerals.
Various minerals occur in India fairly distributed throughout the country and it is depicted as follows.
- Iron ore — It is one of the basic mineral resources. Iron obtained from this ore is the basis of modern Industrial civilization. The four most important ores of Iron are the Magnetite, Hematite, limonite and siderite. The important mining areas are Singhbhum in Jharkhand and Keonjhar, Talcher and Mayurbhanj in Odisha. Other important producers of iron ore besides Jharkhand and Orissa are MP, Chhattisgarh, Goa, Karnataka, Maharashtra and Tamil Nadu.
- Bauxite — It is the ore of Aluminum. The ore is processed to obtain alumina and alumina is further processed to produce aluminum metal. Major areas of mining of this ore are Ranchi and Palamau in Jharkhand. Balaghat and Jabalpur in MP, Bilaspur in Chhattisgarh, Belgaum and thane in Maharashtra, Odisha, Karanataka, and Tamil Nadu are also important producers of aluminum.
- Copper — India is rather poor in copper deposits. Important areas are Agnigundala in Andhra Pradesh; Singhubhum, Mosabani and Rakha in Jharkhand; Malanjkhand in MP; Khetri and Dariba in Rajasthan and Chitradurga in Karnataka. Darjeeling and Sikkim also have some copper deposits. Khetri has the largest copper smelting unit.
- Gold — India is poor in gold reserves also. There are three main areas where gold is mined. Ramgiri gold fields in Anantpur district in Andhra Pradesh, Kolar district of Karnataka and the Hutti mines in Raichur district of Karnataka. Negligible amount of gold is obtained from sands of river Subarnarekha also. Kolar mines are the deepest mines of the world and due to the great depth and declining production the cost of production here are very high.
- Silver- India has poor deposits of silver. Karnataka, Rajasthan, Jharkhand and Tamil Nadu have deposits of silver. Galena and the lead zinc ores of Zawar are the principle sources of silver.
- Diamonds — Diamond is hardest substance and India is rather poor in diamond deposits. They are found in ancient metamorphic rocks. Panna belt in MP is the most important area in India for diamonds. Other areas are in Andhra Pradesh and Karnataka.
- Lead and Zinc- These two minerals generally occur together. Zinc ore occurs in Zawar and Banjawi areas of Rajasthan and in Gujarat. Lead ore is found in Agnigundala in Andhra Pradesh and Sargipalle in Orissa also. Tundu smelter in Bihar processes the lead zinc ores from Zawar area.
- Manganese — India has fairly large reserves of Manganese and the country is one of the leading exporters of Manganese in the world. Orissa, Karnataka, MP, Maharashtra, Goa and Tamil Nadu have the major deposits.
- Mica — It is a non-metallic mineral and India is the largest producer and exporter of Mica. Better deposits of Mica occur in Hazaribagh district of Jharkhand and Gaya district of Bihar, Nellore district of Andhra Pradesh and in Rajasthan. Kodarma mines in Jharkhand are one of the important producing areas. India has almost a monopoly in Mica exports. However with the development of substitutes of this mineral, production of Mica in India has suffered due to declining demand in the world market.
- Limestone- An important raw material for cement, iron and steel industry limestone occurs widely in India. MP, Chhattisgarh, Tamil Nadu, Andhra Pradesh, Gujarat, Bihar, Jharkhand, Orissa, Rajasthan and Karnataka are the important producers. Dehradun region in Uttarakhand also have deposits of good quality limestone.
