Being malleable, ductile and a good conductor , copper is mainly used in electrical cables, electronics and chemical The Balaghat mines in Madhya Pradesh, Khetri mines in Rajasthan and Singhbhum district of Jharkhand are leading producers of copper. Bauxite a clay-like substance that alumina and later aluminium is obtained. deposits are formed by the decomposition of a wide variety of rocks rich in aluminium silicates. Aluminium is an important metal because it combines the strength of metals such as iron, with extreme lightness and also with good conductivity and great malleability. India‘s bauxite deposits are mainly found in the Amarkantak plateau, Maikal hills and the plateau r egion of Bilaspur-Katni. Odisha was the largest bauxite producing state in India Panchpatmali deposits in Koraput district are the most important bauxite deposits in the state. Non-Metallic Minerals Mica is a mineral made up of a series of plates or leaves. splits easily into thin sheets. These sheets can be so thin that a thousand can be layered into a mica sheet of a few centimeters high. Mica can be clear , black, green, red yellow or brown. Due to its excellent di-electric strength, low power loss factor, insulating properties and resistance to high voltage, mica is one of the most indispensable minerals used in electric and electronic industries. Mica deposits are found in the northern edge of the Chota Nagpur plateau. Koderma Gaya – Hazaribagh belt of Jharkhand is the leading producer. In Rajasthan, the major mica producing area is ar ound Ajmer. Nellore mica belt of Andhra Pradesh is also an important producer in the country. Rock Minerals: Limestone is found in association with rocks composed of calcium carbonates or calcium and magnesium carbonates. found in sedimentary rocks of most geological formations. Limestone is the basic raw material for the cement industry and essential for smelting iron ore in the blast furnace. Energy Resources Energy is required for all activities: It is needed to cook, to provide light and heat, to propel vehicles and to drive machinery in industries. Energy can be generated from fuel minerals like coal, petroleum, natural gas, uranium and from electricity. Energy resources can be classified as conventional and nonconventional sources.
RAJESH NAYAK Conventional sources include: firewood, cattle dung cake, coal, petroleum, natural gas and electricity (both hydel and thermal). Non-conventional sources include solar, wind, tidal, geothermal, biogas and atomic energy. Firewood and cattle dung cake are most common in rural India. using dung cake too is being discouraged because it consumes most valuable manure which could be used in agriculture. Conventional Sources of Energy Coal : In India, coal is the most abundantly available fossil fuel.
