Metallic
Ferrous
(In which part of iron is present) Examples :- Iron, manganese, Nickel, Cobalt etc. These account for about three-fourths of the total value of production of metallic minerals. They provide a strong base for development of metallurgical industries. Iron-ore and Manganese are the best examples of ferrous minerals
Iron Ore
- Magnetite - best quality of iron ore, with highest magnetic properties
- Haematite - low quality iron ore
- Major Iron-ore belts:
- Orissa-Jharkhand belt
- Maharashtra - Goa belt
- Bellary-Chitradurga-Chikmaglur-Tumkur belt
- Durg-Bastar-Chandrapur belt
Manganese
- Used in manufacturing of steel and ferro-magnetic alloys.
- 10kg of Mn is used in making of 1 ton of steel.
Non-ferrous
(In which part of iron is not present) Examples :- Copper, Lead, Tin, Aluminium etc. Minerals that do not contain iron content are called nonferrous minerals.
- The reserves and production of non-ferrous minerals in India is not sufficient.
- These minerals include copper, lead, zinc, bauxite, gold etc which are vital for various industries like metallurgical, engineering and electrical industries
Copper
It is an important mineral due to its excellent electrical conductivity. The leading producers of copper in India are:
- Khetri mines in Rajasthan
- Balaghat mines in Madhya Pradesh
- Singhbhum district of Jharkhand
Bauxite
Bauxite ore is used for obtaining aluminium. It is formed by decomposition of a wide variety of rocks rich in aluminium silicates.
- Bauxite is a clay-like substance from which alumina is extracted and later alumina developed into aluminium.
Non-metallic
Example: Mica, Salt, Potash, Limestone, etc.
Mica
It is used in electrical and electronics industries due to its di-electric strength, low power loss factor, insulating properties and resistance to high voltage.
- Mica occurs in the form of plates or leaves, which can be split into thin sheets. Mica can be clear, black, green, red, yellow or brown.
Limestone
Limestone is a rock mineral found in sedimentary rocks. It is composed of calcium carbonates or calcium and magnesium carbonates.
- Limestone is used for smelting iron ore in blast furnaces of steel plants and is the basic raw material for manufacturing of cement.
