Solution
The correct option is B Mica
Answer: The correct answer is option (b) – Mica
Mica
- The leading producer of Mica is the Koderma Gaya – Hazaribagh, in Jharkhand.
- In the northern edge of the Chota Nagpur plateau, Mica deposits can be found.
- In Andhra Pradesh, Nellore belt is the important producer of Mica.
- Major Mica producing region in Rajasthan is the Ajmer region.
- Mica is one of the critical minerals used in electronic and electric industries.
- This is due to many important properties such as resistance to high voltage, insulating properties, low power loss factor, excellent di-electric strength.
- Mica can be clear, black, green, red, yellow or brown.
- Mica is a mineral made up of a series of leaves or plates.
- It can be split into thin sheets, very easily.
- Mica sheet of a few centimeters high can be layered in thousand sheets.
Bauxite
- Aluminium is obtained from Bauxite.
- India’s bauxite deposits are mainly found in the plateau region of Bilaspur-Katni, Maikal hills and Amarkantak plateau.
- Due to the decomposition of a wide variety of rocks rich in aluminium silicates, bauxite deposits are formed.
- Aluminium has great malleability, good conductivity. It is extremely light and combines the strength of iron.
Copper
- The leading producers of copper in India are Singhbhum district of Jharkhand, Khetri mines in Rajasthan, and Balaghat mines in Madhya Pradesh.
- Copper is mainly used in chemical industries, electronics, electrical cables.
- Copper is a good conductor, ductile and malleable.
Iron Ore
- Iron ore is the backbone of industrial development and the basic mineral.
- In terms of the quantity used, Hematite ore is the most important industrial iron ore.
- The major iron ore belts in India are in the states of Karnataka (Ballari- Chitradurga- Chikkamagaluru- Tumakuru belt), in the states of Chhattisgarh and Maharashtra (Durg-Bastar-Chandrapur).
- Iron ore is found in Singhbhum district of Jharkhand,
- Iron ore is found in Mayurbhanj and Kendujhar districts of Orissa.
