Explanation:

Rajasthan is the country’s leading producer of natural Gypsum and Selenite producing about 3.0 million tonnes per year. These are mined in the heart of the Thar desert areas where the working conditions are very harsh. The deposits are shallow and scattered over large areas. Most of the land is owned by private cultivators.

The mining of Gypsum of purity of +70% CaSO4, 2H2O is a co-operative effort between the land owners and RSMML. The farmers gives up his gypsum bearing land to RSMML in return for an assured share of profits. After mining, the Company improves the land condition and returns back to the farmer for cultivation.
