Mineral Resources of India - a review

India possesses huge mineral wealth but it is not much exploited. Coal, gold, mica, building materials, salt, petroleum, manganese ore, iron ore, copper ore and ilmenite are produced in quantities to be of real importance to industry and other sectors of economy. Out of these, mica, manganese ore and ilmenite are largely exported. India has, however, adequate resources of industrial clay, steatite, bauxite, chromite, titanium ore etc.
