Download PDFLimestone is an important ingredient in the Cement manufacturing process. Limestone of varying grades occurs in sedimentary and crystalline rocks. While the high grade deposits are directly utilized for the manufacture of cement and lime, the other varieties are blended with the high grade deposits and made usable. With depleting limestone resources, it is of significance that we explore and exploit all the grade of limestone. Using band ratio technique the occurrence of limestone is identified in Virudhunagar district. Pure limestone will reflect the visible and NIR energy, while SWIR energy in the 2.35μm region will be absorbed. So the ratio chose is7/6 in Landsat 8 data. The depth of absorption in the SWIR region will depend on the concentration of carbonates in the mineral. Hence, it is possible to quantify the purity of a limestone deposit by analyzing the visible and carbonate absorption SWIR bands in a satellite image. And for transporting the materials from the site to factory optimal route is identified using Network analysis
