Major minerals found in the country along with their estimated reserves are given below:
1. Bauxite Ore (Aluminium):
The total in situation reserves is 3.076 million tonnes. About 84 per cent of this reserve is of metallurgical grade. The conditional resources of bauxite are about 5, 99,780 tonnes. In addition, prospective resources are placed at 90 million tonnes.
Orissa, Andhra Pradesh, Chhattisgarh, Gujarat, Maharashtra and Jharkhand are the principal states where bauxite deposits are located. Major reserves are concentrated in the East Coast Bauxite deposits of Orissa and Andhra Pradesh.
2. Chromite:
Total in situ reserves of chromite are estimated at 114 million tonnes. Total geological resources were estimated at 187 million tonnes, consisting of around 114 million tonnes in situ reserves and about 73 million tonnes as conditional resources.
The largest share (about 96 per cent) in the total geological resources is accounted by the Cuttack district in Orissa. Deposits of economic significance occur in Orissa, Karnataka, Maharashtra, Jharkhand, Madhya Pradesh, Chhattisgarh, Tamil Nadu and Manipur. However, refractory grade reserves of chromite are very meagre.
3. Copper:
The total in situ reserves of copper ore in the country are 712.5 million tonnes, equivalent to 9.4 million tonnes of metal content. The all-India conditional resources of copper are 722 million tonnes (3.15 million tonnes of copper metal) and prospective resources are 0.6 million tonnes of copper ore.
Major and important copper ore deposits are located in Singhbhum district (Jharkhand), Balaghat district (Madhya Pradesh) and Jhunjhunu and Alwar districts (Rajasthan). In addition, there are small copper ore deposits in Gujarat, Karnataka, Andhra Pradesh, Uttar Pradesh, Sikkim, Meghalaya, Maharashtra and West Bengal.
4. Gold:
There are three important gold fields in the country, namely, Kolar Gold Fields, Kolar district, Hutti Gold Field in Raichur district (both in Karnataka) and Ramgiri Gold Field in Anantpur district (Andhra Pradesh). Total in situ reserves of gold ore are estimated at 22.4 million tonnes, with 116.50 tonnes of metal.
5. Iron Ore:
The total in situ reserves of iron ore in the country are about 1,23,17,275 thousand tonnes of haematite and 53,95,214 thousand tonnes of magnetite. The resources of very high-grade ore are limited and are restricted mainly in the Bailadila sector of Chhattisgarh and to a lesser extent in Bellary-Hospet area of Karnataka and Barajamda sector in Jharkhand and Orissa.
Haematite resources are located in Orissa, Jharkhand, Chhattisgarh, Karnataka, Goa, Maharashtra, Andhra Pradesh and Rajasthan. Magnetite resources are located in Karnataka, Andhra Pradesh, Goa, Kerala, Jharkhand, Rajasthan and Tamil Nadu.
