   Minerals in Rajasthan

 Rajasthan has the second largest mineral reserves in the country. Rajasthan produces 42 varieties of major minerals and 23 varieties of minor minerals. Presently, the State is the sole producer of jasper and wollastonite and a leading producer of cement and steel grade lime stone, soapstone, ball clay, calcite, felspar, natural gypsum, kaolin, rock phosphate, ochre and building stones besides, tungsten, lead-zinc concentrates, and copper metal. 
Studies by scientists of the Geological Survey of India (GSI) have indicated presence of gold and copper deposits in villages of Alwar and Banswara districts of Rajasthan, GSI Director-General Harbansh Singh said on August 24, 2014
The following Table  shows the minerals found in Rajasthan which account for 70 percent or more of Indiaís total production.
