Leading producers are Italy, Turkey, and China.
Italy produced 4.7 million tonnes of feldspar in 2010.
Turkey produced 4.5 million tonnes of feldspar in 2010.
China produced 2 million tonnes of feldspar in 2010.

Augite

Widespread member of the pyroxene family.
Large crystals are common.
Used in geological studies and by mineral collectors.
Has no commercial uses.

Hornblende

Important constituent of acidic and intermediate igneous and metamorphic rocks
Important component of gneiss and schist.
Main component of amphibolites.
A main component of lamprophyres.

Quartz

Used in the manufacture of glass.
A component of metamorphic rocks in the construction industry.

Calcite

Chemical formula is CaCO3.
Major component of cement and concrete.
Commonly found in a variety of shapes, including rhombohedral and scalenohedral crystals.

Mineral Properties

Color: Can be used to identify minerals but is not always reliable.
Streak: The color of a mineral when it is rubbed against a streak plate.
Hardness: A mineral's resistance to scratching.
Crystal habit: The way a mineral grows, not a reliable diagnostic feature.

Coal

A sedimentary rock.
India has substantial reserves of coal.
There are 574 mines focused on coal production in India

India's Mineral Wealth

India has considerable reserves of iron ore, aluminium ore, titanium ore, and mica.
India also has reserves of copper, lead, zinc, and precious stones.
Rajasthan is an emerging producer of copper, lead, zinc, mica, aquamarine, and emerald.
