2. MINERAL RESOURCES
 A mineral is a pure inorganic substance that
occurs naturally in the earth’s crust. More
than two-thousand minerals have been
identified and most of these are inorganic,
which are formed by the various
combination of elements.
 India produces 4 fuels, 11 metallic, 52 non-
metallic and 22 minor minerals

3. Categories of Mineral Resources
 Mineral resources can be divided into two
major categories.

 1) Metallic Mineral Resources
 2)Non-metallic Mineral Resources


4. 1)METALLIC RESOURCES
 Metallic Minerals are metals that are hard
substance and conduct heat and electricity
with characteristics of luster or shine.
 Examples ;
1)Iron ore
2)Manganese
3)Bauxite

5. 1) IRON ORE
 iron & steel industry largely influences the
economic status of a country Iron ore being
the essential raw-material for Iron & Steel
Industry,
 Following four varieties of iron ore
1)Magnetite
2)Haematite
3)Limonite
4)Siderite
 The total reserves of iron ore in the country
are about 12,317.3 million tonnes of

6. 2)MANGANESE
 The total resources of manganese ore in the
country placed at 430 million tonnes as per
UNFC system. Out of these, 142 million
tone are categorised as reserves and the
balance 288 million tonnes are in the
remaining resources category.
 Odisha tops the total resources with 44%
share

8. 3)BAUXITE
 The Total Resources of Bauxite in the
country are placed at about 3,290 million
tonnes
 These resources include 899 million tonnes
of Reserves and 2,391 million tonnes of
Remaining resources.
 Major deposits are concentrated in the East
Coast Bauxite deposits of Odisha and
Andhra Pradesh

10. 2) NON METALLIC MINERALS
 Non-metallic mineral reserves consist of
stone quarries and clay and sand pits;
chemical and fertiliser mineral deposits; salt
deposits; deposits of quartz, gypsum,
natural gem stones, asphalt and bitumen
 Examples ;
1)Gypsum
2)Mica
3)Limestone
4)

11. 1) MICA
 The total resources of Mica in the country is
estimated at 393855 tonnes
 Rajasthan accounts for about 51 per cent
resources, followed by Andhra Pradesh
Maharashtra and Bihar.
 Uses of Mica
a)Used in paints to brighten the colour
b)Used in electronic equipment
c)

13. 2)LIMESTONE
 The total resources of limestone in India is
175345 million tonnes.
 Karnataka is the leading state followed by
Andhra Pradesh, Gujarat, Rajasthan.
 Uses
A)It is the raw material for the manufacture of
cement
B)t is added to toothpaste, paper, plastics,
paint, tiles

15. 3)GYPSUM
 The total resources of mineral Gypsum is
1,237 million tonnes
 The main occurrences of gypsum are
located in Rajasthan, Jammu and Kashmir,
Gujarat and Tamil Nadu
 Gypsum is a soft sulfate mineral composed
of calcium sulfate dihydrate, with the
chemical formula CaSO4·2H2O.
 It is widely mined and is used as a fertilizer,
and as the main constituent in many forms
of plaster, blackboard chalk and wallboard
