ECONOMIC IMPORTANCE OF MINERALS The significance of mineral resources embraces several areas. They are an integral part of industrial development , economic progress and national  security . Mineral resources are related to significant economic activity  that converts natural mineral wealth into goods for industrial and domestic  consumption. Minerals  are important  to our health, we need small amounts of a wide variety  of minerals like calcium, phosphorus, sulphur, copper, floride, iron and zinc. coal, oil and natural  gas provide us with almost all of he energy we use to light, heat and run our world. Minerals are ingredients  in almost all  of the products we use from fertilizer, plastics, toothpaste, medicines. Minerals also play an important  role in the processing of materials. Bentonite is important  in well drilling and Barite is important  in oil drilling . Chert used to make stone tools and used as fill to provide stable base for roads. Coal used as a fuel (

Along with 48.83% arable land India has significant sources of  c oal (fourth-largest reserves in the world), bauxite, tiranium ore,  c hromite, natural gas, petroleum and limestone.According to the 2008 Ministry of Mines estimates: 'India has stepped up its production to reach the second rank among the  c hromite producers of the world. Besides, India ranks 3rd in production of coal & Lignite, 4th in iron ore, 5th in bauxite, 7th in manganese ore and 8th in aluminium. Indian mines majorly accounts the future prospective of surface mining. With this vast knowledge of surface minin

Clean Coal Technology The term Clean coal technology means any technology deployed at a new or existing facility which will achieve significant reduction in air emissions of sulfur dioxide or oxides of nitrogen associated with the utilization of coal in the generation of electricity. Indian systems and technologies adopted are ancient times and case studies acquired that time but now the changing requirements of our nation is basically dropped from 40j/kg to 27.8j/kg over past 50 years. Nowadays Indian policies are changing to the environmental responsibilities.
