India is richly endowed with minerals.
India possesses more than 100 minerals.
Out of 100 minerals, there are 30 minerals which have economic significance.
Some of the examples are coal, iron ore, manganese, bauxite, mica etc.
The situation is also satisfactory in feldspar, fluorides, limestone, dolomite and gypsum etc.
But the reserves of petroleum and some nonferrous metallic minerals especially copper, lead, zinc, tin, graphite are inadequate.
Non-ferrous minerals are those which do not contain iron.
If we look at mineral wise break up it has been found that fuel minerals (coal, petroleum, natural gas and lignite) accounted for about 77%, metallic minerals for about 10% and non-metallic minerals for about 3% of total value of minerals produced.
Metallic minerals– Iron ore, Chromites, Manganese, Zinc, Bauxite, Copper and Gold
Non-metallic minerals– Limestone, Phosphorite, Dolomite, Kaolin, Magnesite, Barytes and Gypsum.
