Rajasthan is a state that is rich in minerals. The Rajasthan state is sanctified with seventy-nine mineral varieties out of which fifty-eight minerals are commercially subjugated. Rajasthan has effective domination in the manufacturing of major minerals like Lead-Zinc, Wollastonite, Gypsum, Calcite, Ochre, Silver, Rock phosphate and other minerals like Sandstone, Serpentine, Marble, etc., that contributes around ninety percent to hundred percent of national production.
Massive reserves of Crude oil, Lignite, Heavy oil, Lean gas and Bitumen further add to the state’s mineral strength. Rajasthan contributes appreciably in the production of Lead, Copper and Zinc.
Apatite crops up as a main ingredient of igneous rocks, but as an ornamental mineral. It also crops up as a layer mineral. It is natural phosphate mineral having a specific chemical symphony. In Rajasthan, apatite mineral occurs in the districts of Udaipur and Sikar.
Rajasthan constitutes around 96 percent of India’s entire asbestos production. The deposits of asbestos are chiefly located in the south of Rajasthan state. Asbestos is limited to the tainted ultramafic intrusives inside the rocks of the Aravalli, Delhi supergroups and Bhilwara. Rajasthan state possesses amphibole and chrysotile varieties of asbestos.
Bauxite is a mineral that is used chiefly for aluminum metal extraction in the chemical as well as refractory industries, emery powder manufacturing, petroleum products refining and cement paint. Rajasthan contributes very irrelevant bauxite quantity predictable at 3 million tonnes. It is found in Udaipur, Rajasthan.
Beryl is the silicate of aluminum and beryllium. Beryl is the major source of beryllium that is comparatively lighter than aluminum metal. When Beryl is alloyed with copper and heated, the alloy builds up high tensile potency and capability to endure repeated pressure. Beryl occurs in alliance with mica pegmatite in mica mines of Udaipur, Bhilwara and Ajmer districts.
The areas of South-Eastern Rajasthan are partially engaged by Deccan Traps which comprise the chief building stone in this region. The Rhyolite mineral is typically used for railway ballast and various other building uses in the western Rajasthan. The quarries are situated at Chechat, Ramganj Mandi, Manpura, Suket, Morak and Kota. The flaggy limestone also arises near Paroliya, Kishanpura and Aroutiya in Jhalawar district.
The occurrences of granite Rajasthan are dispersed over extensive areas in Alwar, Ajmer, Barmer, Chittaurgarh, Dungarpur, Banswara, Jhunjhunun, Jaipur, Bhilwara, Jodhpur, Jalor, Jaisalmer, Pali, Sawai Madhopur, Sirohi, Sikar, Nagaur, Rajsamand, Udaipur and Tonk districts.
Marble is largely excavated from Rajnagar, Rikhabdev, Andhi, Makrana, Bhaislana and Ajmer areas.
Rajasthan is one of the major centers of sandstone export. The significant occurrences of sandstone are found inBikaner, Bharatpur, Jaipur, Bundi, Jodhpur and Kota districts.
