2. What are Minerals?
• Minerals are associated with igneous
and metamorphic rocks. They are
exhaustible resources. Rocks
containing metallic minerals in
concentrated form are called ores.
Mineral ores are to be refined before
their use.
• Social and economic development of
a country depend on its capacity to
utilize its mineral resources.

&NORGANIC ORIGIN WITH DEFINITE PHYSICAL & CHEMICAL
PROPERTIES]
4. IRON ORE
• Hematite and magnetite are by far the
most common types of ore. Pure
magnetite contains 72.4 percent iron,
hematite 69.9 percent, limonite 59.8
percent, and siderite 48.2 percent, but,
since these minerals never occur alone,
the metal content of real ores is lower.
Siderite is the poorest grade of iron ore.
Hematite ores are found in the
peninsular region.

6. Distribution of Iron ore
• Jharkhand- Noamundi, Gua of Singbhum district
• Orissa- Keonjhar, Mayurbhanj, Sundargarh
• Karnataka- Bababudan hills, Kalahandi, Kemangudi,
kudremukh. Kudremukh in Chikmagalur has magnetite
deposits which are meant for export.
• Chhattisgarh- Bailadila in Bastar, Dalli Rajhara in Durg
District, Bilaspur
• Goa’s ore are chiefly shipped Japan. The primary use of
iron ore is in the production of iron. Most of the iron
produced is then used to make steel. Steel is used to
make automobiles, locomotives, ships, beams used in
buildings, furniture, paper clips, tools, reinforcing rods for
concrete, bicycles, and thousands of other items.
7. USES OF IRON ORE
• Iron ore is used for the
production of iron – a key
ingredient for
manufacturing of steel – all
machineries and
engineering products are
made of steel
• Steel is used for making
automobiles, locomotives,
ships, beams etc
• Used in building dams,
bridges and major
structures
8. MANGANESE
• Uses Of Manganese
• Manganese is used to produce a variety of important alloys and
to deoxidize steel and desulfurize, increases the strength of
steel, chemical industries for manufacturing bleaching powder
• It is also used in dry cell batteries.
• Manganese is used as a black-brown pigment in paint.
• It is an essential trace element for living creatures.
9. USES OF
MANGANESE
• Important mineral in the making of steel. It strengthens steel
when mixed with iron
• Used as a raw material for manufacture of paints and glass
• Used in manufacturing of dry cell batteries
• Making of agricultural fungicide which is widely used in
controlling crop and cereal diseases
• Used in manufacturing of bleaching powder
10. DISTRIBUTION OF
MANGANESE
• Odisha- is the leading producer-
Sundergarh, Koraput and Sambalpur
districts.
• Karnataka- is the second largest
producer, Shimoga, Bellary and
Chitradurg and Tumkur district.
• Maharashtra- Nagpur and Bhandara
districts. Ratnagiri is famous for high
grade iron ore.
• MP- Chindwara and Balaghat districts
11. COPPER
• Copper is a non-ferrous metal.
• It has excellent ductility
• High conductivity of heat and electricity
• Resistance of corrosion and ability to form
alloys with other metals. It is soluble in
gold.
USES-
Copper is ideal for making electrical wires.
It is used to make water pipes, utensils,
coins, alloys and decorative goods.
12. DISTRIBUTION OF
COPPER
• MP- Largest producer. Balaghat is
the main mining area.
• Rajashthan- Alwar and Jhunjhunu
• Jharkhand- Singhbhum district
• Andhra Pradesh- Guntur and
Kurnool districts
• Karnataka- Chitradurg and Hasan
