India Mining and Quarrying Country Studies
Mining accounted for less than 2 percent of GDP in FY 1990. Nonetheless, iron and bauxite are found in sufficient quantities to base industries on their extraction and processing. Assessment of the country's resources by the Geological Survey of India is still far from complete in the mid-1990s, and observers do not rule out the possibility of important ISIC 07 Mining of metal ores 08 Other mining and quarrying 099 Support activities for other mining and quarrying SICS® EM-3 Metals and Mining, with the exclusion of the manufacturers of aluminum and steel, and metal recycling Sustainability impacts The key criterion for prioritizing sectors is their sustainability impacts.GRI Sector Standards Project for Mining Global Reporting

Total employment of all mining and quarrying establishments reached 38,825 in 2012, an increase of 44.7 percent from 26,834 workers recorded in 2010. Almost one-third (31.8%) of the total employment or 12,362 workers were employed by nickel ore mining establishments, followed by copper ore mining with 8,242 workers or 21.2 Support activities for mining, and oil and gas extraction grew 3.3% in August, mainly as a result of increased drilling activity. StatCan added that the mining and quarrying (except oil and gas) subsector contracted 0.8% in August as a result of a decrease in metal-ore mining. All metal-ore mining industries decreased, with the Canada's mining, quarrying and oil and gas extraction fell 1

Open-pit mining provides significant proportions of many of the world's major mineral commodities. Much of the world's annual output of copper, gold and iron ore is won from open-pit operations. Other commodities produced from open-pits include diamonds, molybdenum, manganese, lead and zinc, uranium and a variety of industrial minerals, In open-pit mining a large proportion of the matter which is removed from the mine is processed and then discarded. Miners are searching for minerals such as copper, gold or iron ore for example. The rock and earth removed from the mine in the first instance is not the target for the miners, but the above mentioned minerals which exploration technics Surface Mining & Quarrying Techniques & Methods Epiroc
