The National Metallurgical Laboratory in the development of Mineral Beneficiation and Extractive Metallurgical Techniques

Abstract

In the context of India's mineral resources, the author discusses researches on mineral beneficiation and deve-lopments in extractive metallurgical techniques, and outlines the role of the National Metallurgical Labo-ratory in this respect. General particulars are furnished of the work done on beneficiation of manganese, chromite, graphite, pyrites, etc., and of the extractive metall-urgical themes under development at the Laboratory, in-cluding pilot plant investigations on electrolytic mang-anese and manganese dioxide. A review of the Laboratory's programme of work during the second Plan, which includes the setting up of pilot plant projects on thermal bene-ficiation of low-grade manganese and chromite ores and the treatment of low-grade manganese, chrome and other ores by ore-dressing methods, is also given.
