Abstract: Gypsum is a naturally occurring mineral produced in many parts of the India and the world. Chemically it is hydrated calcium sulfate. The chemical formula for pure gypsum is Ca(SO4)•2(H2O). In the chemically pure form, gypsum contains 23.28% calcium (Ca) and 18.62% sulfur (S) in the readily available sulfate form (SO4). However, the typical gypsum sources that are commercially available for agricultural often contain impurities which result in a Ca level between 16%-23% Ca and 15%-19%.Rajasthan produces 99% of the total mineral Gypsum production in India. And most promising depostis occurs in Bikaner Distt. As demand is increasing so there is need for prospecting new promising areas of Gypsum/Gypsite . This research paper would help in meeting the increasing demand of natural Gypsum with the search of new deposits in Bikaner Distt.It would also help in generating revenues to the Govt.
