Mapping of Granite and Marble Slurry sites of Rajasthan
Rajasthan is known as Museum of minerals in India. It owns 79 different types of Major and Minor minerals. It shares 9% of the mineral production in India. Mining and smelting of its base metal deposits are also one of the oldest in the world dating back to more than 2,500 years before present. Rajasthan is also Known for its decorative stones; Marble and Granite. Marble has been mined here for last 400 year. Taj Mahal & Victoria palace is built by Rajasthani Marble. But nowadays Rajasthan is paying the heavy price of stone mining & processing. The waste generated from Mining and processing from conventional techniques is very high & sometimes it is up to 70% of the total mined block. The waste remains in the form of odd blocks, unshaped rock fragments, Krazzy and stone slurry. All the other waste except the slurry can be used directly for various purpose. The slurry causes different pollution like air pollution, land pollution, water pollution and visibility pollution when it is dumped unscientifically. There are 7 Tehsils of Rajasthan which are affected by this problem. In this study, the locations of the Slurry dumping sites (both scientific & unscientific) has mapped & the total area which falls under the slurry site is calculated. Though this mapping is conducted with simple techniques but the study will help in prepare a data inventory of these pollutant slurry sites. It can be further used in Site suitability analysis of the slurry sites.
