@article{Mamanduru_2015, title={SUSTAINABLE MINING ACTIVITY IN THE NELLORE MICA BELT THROUGH EXPLORATION OF COLTAN DIPOSIT}, url={https://innoriginal.com/index.php/iijs/article/view/30}, abstractNote={<span>Coltan is  a dull metallic ore found in major quantities in the Nellore mica belt and also found in eastern areas of the Congo possesses 80 percent of the world’s coltan. Biswas (1935) [1] made an examination of the pegmatite and considered them to have magmatic origin in accordance with the Bowen’s reaction principle. Ghosh visited the area in the field season 1932-1933 at the request of the Madras Government to investigate the behaviour of Nellore mica deposits at depth and the relationship between the country rocks and mica-bearing pegmatites (Fermor, 1935) [2]. He also described the occurrence of minerals such as beryl, coltan and samarskite in the pegmatites and minerals like garnet, kyanite and talc in the country rocks. The main objective of  to determined from the spectrums obtained from SEM with EDS in the methodology of use, subjecting sample so collected though qualitative chemical analysis, C1 to C12 analysis of SEM with EDS. </span>}, journal={Innoriginal: International Journal of Sciences}, author={Mamanduru, Suresh}, year={2015}, month={Dec.} }
