Mining At A Glance
Rajasthan has a glorious heritage in the field of mines and minerals. The State is geologically so endowed that it has become a veritable depository of minerals. Important minerals with which the name of this State is intimately associated are that of non- ferrous metals (lead, zinc, and copper) and ferrous minerals such as tungsten and a number of industrial minerals. Presently, the State is the sole producer of jasper and wollastonite and a leading producer of cement and steel grade limestone, soapstone, ball clay, calcite, felspar, natural gypsum, kaolin, rock phosphate building stones besides, tungsten, lead-zinc concentrates, and copper metal.
Cement Grade Limestone
Rajasthan in endowed with vast resources of limestone with estimated reserves of abut 7000 million tonnes. The important limestone bearing areas within the State are located in the districts of Chittorgarh, Bundi, Bhilwara, Kota, Nagaur, Pali, jaisalmer, Jodhpur, Jaipur, Banswara etc.
Granite
In Rajasthan, a number of workable deposits of granite have been located in Jalore, Barmer, Sirohi, Pali, Ajmer, Jaipur, Sikar, Jhunjhunu, Dausa, Alwar, Tonk, Bhilwara, Rajsamand, Udaipur, Dungarpur, Banswara, Chittorgarh and Sawai Madhopur Districts.
The State Government has formulated a new policy for granting mining leases of granite over the plots delineated by the Department, with a view to ensure systematic mining through deployment, of proper machinery and equipment and to promote the export of processed granite. Under this policy, preferential allotment has been provided to entrepreneurs who have installed or who propose to install export printed processing units in a stipulated period.
Marble
Rajasthan with the total estimated reserves of about 1000 million tonnes, contributes about 90% of the country's production of this decorative stone. Important deposits of marble occur in Nagaur (Makrana), Rajsamand, Banswara, Dungarpur, Udaipur, Sirohi, Jaipur, Alwar, Ajmer and Chittorgarh districts.
Base Metals
A number of small base metal deposits occur in Udaipur, Sirohi, Bhilwara, Chittorgarh and Jhunjhunu districts in the State. Which may now be made available for grant of mining leases to private entrepreneurs.
