5. The main iron ore deposit in INDIA are :- Chhattisgarh Jharkhand Odisha Karnataka Goa Andhra Pradesh Tamil Nadu Rajasthan

6. manganese Manganese is a black, hard and iron-like metal which occurs as natural oxide. It is an important raw material for smelting of iron ore and also used for manufacturing ferro alloys.

7. Uses of manganese Manganese is used in dry cell batteries. Manganese is used to make steel tough and resistant to rusting. Manganese is used to manufacture black enamel.

8. Manganese is mined in the following areas: Madhya Pradesh Telangana Goa Jharkhand Karnataka Maharashtra Odisha Rajasthan

9. copper Copper is an important non-ferrous metal used by man. In nature, copper occurs in the native form and in three principal combinations, that is, sulphides, oxides and carbonates.

10. Uses of copper It is good conductor of electricity, highly ductile and malleable and is therefore, used for making electric wires. It is alloyed with iron and nickel to make stainless steel, which is used to make utensils and other objects. It is used in building construction for roofing and plumbing

11. The main areas where copper is found in india are: Madhya Pradesh Rajasthan Maharashtra Andhra Pradesh

12. Bauxite Bauxite is an oxide of aluminium. It is found mainly in tertiary deposits and is associated with laterite rocks occurring extensively either on the plateau or hill ranges of peninsular India.
