Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO₃) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters

In sedimentary rocks a number of minerals occur in beds or layers. They have been formed as a result of deposition, accumulation and concentration in horizontal strata. Coal and some forms of iron ore have been concentrated as a result of long periods under great heat and pressure. 

Bauxite is the most important ore of aluminum which contains only 30–54% alumina, Al2O3; the rest is a mixture of silica, various iron oxides, and titanium dioxide along with trace amounts of zinc, phosphorous, nickel, vanadium etc

Hematite, also spelled as haematite, is a common iron oxide with a formula called Fe2O3 and has been widespread in rocks and soils

Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS)

The mineral monazite is a reddish-brown phosphate containing rare earth metals and an important source of thorium, lanthanum, and cerium

 India's largest solar power plant is located in the Kamuthi in Tamil Nadu spread over 2,500 acres (10 sq km) and consisting of 2.5 million solar panels.

Kolar in Karnataka has deposits of gold in India. These mines are among the deepest in the world which makes mining of this ore a very expensive process. 

Mica is a mineral made up of a series of plates or leaves. It splits easily into thin sheets. These sheets can be so thin that a thousand can be layered into a mica sheet of a few centimeters high. 

Minerals can be extracted by mining, drilling or quarrying. For minerals near the surface quarrying is done to extract them.

India is the largest producer and exporter of mica in the world. Mica deposits mainly occur in Jharkhand, Bihar, Andhra Pradesh and Rajasthan.
