Welcome dear students! Today we are going to learn about India - Mineral and Power Resources from Class 10 Social_Science. We will explore the introduction to the minerals of India and their importance, the distribution and production of major minerals, the need for non-conventional energy sources like solar power and wind power, the scarcity of energy resources, their conservation and solutions, and the causes of scarcity of energy resources. Minerals are the most important natural resources. A compound of naturally available substance with specific chemical composition is called a mineral. Minerals are available along with rocks in the surface of the earth. Among them, iron ore, manganese ore, bauxite ore, mica and gold are very important. In addition to these, energy resources like coal, petroleum and atomic minerals are also produced in the country. In view of the shortage of electricity in the country, non-conventional energy sources like solar power and wind power have become very important. [CHECKPOINT]
Let us begin with iron ore. Iron ore is the most important ferrous and metallic mineral produced in India. Of the total value of minerals production in the country, iron ore constitutes about 20 percent. India ranks 6th in the world in terms of iron ore deposits. In India, Jharkhand, Odisha and Karnataka states have maximum iron ore deposits. Singhbhum of Jharkhand, Keonjhar, Mayurbhanj and Sundargarh of Odisha districts have huge deposits of iron ore. Bastar, Durg and Raipur districts of Chhattisgarh, Goa, Andhra Pradesh and Tamil Nadu also have iron ore deposits. In Karnataka, Kemmangundi, Hospet, Sandur and Kudremukh have large deposits of iron ore. The iron ore produced in India is being used for iron and steel industries of Karnataka, Chhattisgarh, Jharkhand, West Bengal, Madhya Pradesh, Odisha, Tamil Nadu and Andhra Pradesh. Besides, the ore is being exported to Japan, China, Italy, Iran and other countries, thereby earning foreign exchange. [CHECKPOINT]
Do you know this? Based on the metal and impurities content, iron ore is classified into four types: Magnatite, Heamatite, Limonite, and Sederite. Next, we will learn about manganese ore. Manganese is the most important of the ferro-allied ores mined in India. Manganese is used in the manufacture of steel. It is also used in manufacture of chemical and electrical equipment and colored glass. The main types of manganese ore are Pyrolusite, Psilomelane, Manganite, Braunite and Hollandite. The manganese ore extracted in India is of the best quality. Pyrolusite and Psilomelane are important manganese ore. Odisha, Karnataka, Madhya Pradesh and Maharashtra are the important manganese-producing states. In addition, Bihar, Chhattisgarh, Rajasthan, Punjab and Goa also produce manganese ore. [CHECKPOINT]
Now let us move on to bauxite ore. Bauxite is the important ore of Aluminium. It is mixed with sand and iron oxide. Being brownish yellow and grey in colour, Bauxite is sticky like clay in nature. Bauxite has about 60 to 70 percent of Aluminium oxide and by melting this, Aluminium metal is obtained. Aluminium is used in various industries. It is called the Wonder Metal of the 20th century. Bauxite is mainly used in the production of Aluminium metal. India has huge Bauxite deposits and is also self-sufficient in aluminium production. India ranks 5th in the world in Bauxite deposits. Bauxite is available in plenty in Koraput, Kalahandi, Bolangir, Sundergarh districts of Odisha, Jamnagar, Bhavnagar, Junagadh, Bharuch and Surat districts of Gujarat, Ranchi, Palamu, Jaipur, Lohardaga of Jharkhand, Ratnagiri, Kolhapur, Ambolighat, Udayagiri, Radhanagari, Dungarvadi of Maharashtra, Bastar, Bilaspur, Raigad and Surguja districts of Chhattisgarh. In addition, Madhya Pradesh, Belagavi of Karnataka, Salem and Madurai of Tamil Nadu, Vishakapatnam of Andhra Pradesh also have Bauxite deposits. Saudi Arabia, the United Arab Emirates, Britain, Germany, Japan and the United States of America import Bauxite from India. [CHECKPOINT]
Let us now study mica. Mica is a very important non-ferrous mineral. India is in a leading position in having deposits of mica and in the manufacture of mica plates. Mica is a transparent, heat-resistant, shiny silicate mineral with elasticity. Mica has some qualities; the important among them are insulation and elasticity. It is used in the manufacture of telephones, telegraph, wireless service, glass, colour varnish, artificial rubber, dynamos and chemical industries. Mica is also called Kage bangara in Kannada. Based on the chemical composition and colour, mica is divided into many types. They are Muscovite which is white, Biotite which is black, Phlogopite which is brown, and Lepidolite. India has plenty of the best variety, that is, Muscovite. Mica is found in Sri Potti Sriramulu Nellore district of Andhra Pradesh, Warangal of Telangana, Krishna and East Godavari districts, Dhanbad, Palamu, Giridh and Kodarma of Jharkhand, Gaya, Mongair, Bagalpur, Naoda districts of Bihar, Udaipur, Ajmira, Bilwara, Jaipur rural districts of Rajasthan, Trivandrum of Kerala state, Salem of Tamil Nadu, Chindwara, Bastar in Chhattisgarh and Balaghat of Madhya Pradesh. In early period, India was a leading exporter of Mica. Today, because of the availability of substitute for mica, its export has reduced. [CHECKPOINT]
Next, we come to gold ore. Gold is the valuable metal, and has been popular since ages. Gold is used as a standard in fixing the value in the international money market. India has insignificant gold deposits. KGF in Kolar, Raichur and Hatti and Kappatagudda of Gadag mines of Karnataka, Anantpur of Andhra Pradesh, Bihar, Kerala and Tamil Nadu have some deposits of gold ore. In addition to this, it is found in the form of fine threads in the igneous rocks of Kappatha Gudda in Gadag. At present, Hatti is the largest producer of gold in the country. [CHECKPOINT]
Now let us shift our focus to power resources. Power resources are essential for the economic development of the country. Conventional power resources are those which can get exhausted. Examples are coal, petroleum, and atomic power. Non-conventional power sources are those which are not exhaustible. Most important of them are solar power, wind power and hydro-electric power. Let us start with coal. In India, the most important power resource is coal. India ranks 3rd in the world in the production of coal. It is said that millions of years ago, the earth was covered with thick dense forests, and these forests gradually buried in the layers of the earth and converted into coal due to heat and pressure. Coal is not only an energy source, but also used in the manufacture of insect repellants, explosives, artificial fibre, artificial rubber, plastic, and chemical fertilizer. Coal being an important mineral product with multiple uses, it is called Black Diamond. In India, coal deposits are widely distributed in Damodar river valley. Jharkhand and Chhattisgarh are the states producing largest amount of coal. Jharia, Giridh, Bokaro and Karanpur are the main fields of Jharkhand. Besides, Godavari, Mahanadi and Vardha river valleys have coal deposits. The states producing coal are Jharkhand, Chhattisgarh, Odisha, West Bengal, Andhra Pradesh, Telangana and Madhya Pradesh. In India, there is a great demand for coal and hence it is importing superior quality coal. [CHECKPOINT]
Do you know this? Based on the carbon content and calorific value, coal is divided into four types: Anthracite, Bituminous, Lignite, and Peat. Let us move on to petroleum. It is believed by scientists that petroleum is the product of fossils of ancient living beings. Petroleum pumped out of the earth is a mixture of various materials and is called Crude Oil. This is purified in refineries to produce gasoline, petrol, diesel, and kerosene. Petrol is not only an energy source but also an important raw material. A number of industries have flourished using this as a raw material. Petroleum is a very important energy resource in agriculture, industry and transportation. It is very precious during both peace and war. Hence it is called Liquid Gold. In India, petroleum was first discovered at Digboi of Assam. Till independence, Digboi was the only region of petroleum products. Today, Lakhimpur, Hugrijin, Moran, Naharakathia and other oil wells of Assam are producing petroleum. Gujarat is a state that produces crude oil. The first well was drilled in Ankaleshwar. In the year 1974, crude oil was identified about 110 kilometres away from Mumbai in the offshore field called Bombay High and the production was started in 1976. This is the biggest oil deposit of India. Recently, oil deposits have been discovered in Kaveri, Krishna, Godavari and Mahanadi river basins. Today, there are about 23 refineries producing petroleum. The petroleum production is not sufficient in India, crude oil is being imported from Iran, Iraq, Saudi Arabia and Russia. [CHECKPOINT]
Next, we will study atomic minerals. India has plenty of atomic minerals. Atomic power is generated using these atomic minerals. Atomic power decides the status and might of a nation. Atomic power was used only for a country defence in the earlier days. But today, it is being widely used for power generation. The important atomic minerals found in India are Uranium, Thorium, Berylium, and Lithium. Uranium is distributed in Singhbhum and Hazaribagh of Jharkhand, Gaya of Bihar, in the loamy soil of Saharanapur of Uttar Pradesh, and in the sandy coasts of Kerala. Thorium can be found in Kerala, Bihar, Tamil Nadu and Rajasthan. Berylium oxide is used as a catalyst or moderator in reactors producing nuclear energy. India has sufficient deposits of berylium. Lithium is a light metal obtained from lepidolite and Spodumene ores. It is found abundantly in Jharkhand and Madhya Pradesh. [CHECKPOINT]
Now let us discuss non-conventional energy sources. All over the world, due to the use of conventional energy sources like coal, petroleum, natural gas and other fossil fuels, the phenomenon of green-house effect and consequent increase in temperature of the earth atmosphere is being noticed. This is called global warming. Population increase, urbanization, and industrialization have also led to the increased use of fossil fuels. Due to this, environmental pollution is also increasing. Today, it is essential to reduce the use of such fuels and to use non-conventional energy sources. Renewable energy sources like solar energy, wind energy, tidal energy, geothermal energy, and bio-gas are called non-conventional energy sources. First is solar energy. Use of the heat emitting from the sun rays is called Solar Energy. This is a renewable source of energy, and the solar power is directly converted into heat energy. Solar energy is already being used in a variety of ways like solar water heater, cooker, solar electric bulb, railway signal, to lift water and in communication media. India's first solar electricity production center is being proposed to be set up at Baramar in Rajasthan. Recently, a solar electric station was set up in Pavagada of Tumakuru district in Karnataka. Second is wind power. In India, wind power is being produced on a commercial purpose and in the future, many parts of the country would be using wind power as the main source of electricity. India is the 5th country in the world to produce wind power. Tamil Nadu, Maharashtra, Karnataka, Rajasthan and Gujarat are establishing wind power stations. [CHECKPOINT]
Let us understand the need for non-conventional energy. In India, of the energy resources being used, the exhaustible energy resources are the main ones. It has become inevitable to use non-conventional energy sources to conserve the conventional energy sources. Exploration and use of non-exhaustible energy uses has gained a lot of importance in the five-year plans. It has become inevitable in our country to take necessary steps to prevent the deficit in the energy resources. The steps are as follows. One, use of non-conventional resources. Two, giving importance to hydro-electric power generation. Three, use of alternate local energy resources. Four, encouraging the use of non-conventional energy resources. Five, educating the people regarding the reduced use of energy resources. Six, producing energy from solid waste. Regarding the maps in your textbook, one map shows the distribution of iron and manganese ore across states like Uttarakhand, Haryana, Rajasthan, and Odisha. Another map illustrates the locations of bauxite, mica, and gold deposits across the country. A third map highlights the Arabian Sea, Bay of Bengal, Jharkhand, and the Kalpakkam nuclear power station location. These maps visually represent the geographical spread of these vital resources.
