Minerals and Energy Resources Long Answer Type Questions
Question 1.
Comment on distribution of iron ore in India.
Answer:
India is the second largest country of iron ore deposits after Russia. Five types of iron ores are found in India and they are magnetite, hematite, ciderite and laterite. The total iron ore deposit in India is 2300 crore tonne which is 20% of the world’s deposit. Out of total iron ore deposit in India magnetite (60 to 70% iron) is 8%, hematite (70 to 80% iron) is 85% and rest 7% is composed of other types of iron ore. Production in distribution of iron ore in India is as follows:
1. Odisha: Odisha has 30% of the country’s iron ore deposits and it produces about 28% of iron in India. Deposits of hematite iron ore are present in-Mayurbhanj, Sundargarh and Keonjhar districts. Gurumahisini, Sulempat and Badam hills of Mayurbhanj district, Baspani, Thakurani and Kiruburu of Keonjhar district are the main mines of iron in Odisha. Iron ore from Odisha is exported to Japan and other countries from ports at Vishakhapatnam and Paradip.
2. Karnataka: Karnataka has 25% of country’s iron ore deposit and it produces 26% of iron. Deposits of hematite iron ore are present in Bellary, Chikmaglur, Chitradurga and Shimoga districts. Bababudan hills, Kalahari, Kemangudi and Kudremukh are the major mines of iron in Karnataka. Iron and steel plants are present at Bhadravati and Vijaynagar.
3. Chhattisgarh: This is the third largest producer of iron in India. Chhattisgarh has 16% of iron ore deposits in India and it contributes 15.02% of total iron production. Deposits of hematite ore are present in Bastar, Durg, Dantewada, Bilaspur and Rajnandgaon districts.
Question 2.
What is the contribution of minerals in Indian economy?
Answer:
Minerals have immense contribution in Indian economy. We cannot imagine even our day to day life without minerals.
Significance of minerals in the Indian economy can be explained as follows:
- Minerals supply raw materials to key industries like iron and steel industry, automobile industry, pharmaceuticals industry, paint, tanneries, chemicals, etc.
- Coal and petroleum are the important fuels, and industry cannot function without fuels. Coal is the main fuel being used in industries. Coal is primarily used in thermal power plants and in iron and steel industry. In fact, coal is so important for industry that it is called the mother of industries.
- Iron ore is essential for almost all industries because iron is an integral component for all the machines and tools. Moreover, iron is used in making large buildings and factories.
- Iron is also important for making farm equipment’s.
- Other metals are also useful for making various products and hence minerals of these metals are important.
- By promoting industries minerals help in employment generation. Many minerals earn valuable amount of foreign exchange through export.
Question 3.
Explain the availability of petroleum in India.
Answer:
Deposits of petroleum are found in the Brahmaputra and Surma basins of Assam, Sunderbans Delta in West Bengal, east coast of Odisha, Surashtra & Rajasthan, terai belt of Himalaya, mid-Gujarat, Mumbai Basin ,Godavari and Cauveri Delta, etc.
About 90% of total petroleum production comes from Maharashtra, Assam, Gujarat and Rajasthan. The crude oil is sent to 24 large refineries through pipelines.
Some of the refineries are at Guwahati, Barauni, Vadodara, Haldia, Mathura, Digboi and Jamnagar. Deposits of natural gas are in Tamil Nadu, Himachal Pradesh, Punjab, Rajasthan, West Bengal, Tripura and Arunachal Pradesh. Natural gas production in India is managed by the public sector company Oil and Natural Gas Commission (ONGC). This company provides natural gas for electricity generation (38%), fertilizer production (33%), and to other industries and for domestic fuel, country’s 91% production of natural gas comes from Maharashtra (71%), Gujarat (11%), Assam (7%) and Rajasthan (2%).
Question 4.
Comment on availability of coal in India.
Answer:
In India 98.5% of coal deposit (which contributes 99% production) is present in sedimentary rocks of the Gondwana epoch. These deposits are present in the Mahandi basin, Damodar basin, Son basin, Godavari-Wardha and in the basins of Brahmani, Indravati, Koel and Panch rivers. The Bituminous coal is found in the form of 10m to 30m thick layers in these areas. ,
India also has deposits of low grade lignite coal from tertiary period. These deposits were made around 15 to 60 lakh years ago. Such deposits of coal are present mixed with limestone. Deposits of lignite coal are found in Assam, Meghalaya, Arunachal Pradesh, Himachal Pradesh, Nagaland and Rajasthan.
