In the long term, this should be carried out for REEs as well, so that new technologies are not dependent on such high cost products. Cost Analysis. Opening a mine and separation plant can cost from $500 million to $1 billion, depending on the location, element, ore grade, and a .

Copper production in India is only about 2 percent of world copper production in view of its potential reserve limited to 60,000 km 2 (2% of world reserve) of which 20,000 km 2 area has been subject to exploration, as of 2012. But in production it is still within the first 20 countries of the world and also one of its largest importers in line with China, Japan, South Korea and Germany.

The Mining industry in India is a major economic activity which contributes significantly to the economy of India.The GDP contribution of the mining industry varies from 2.2% to 2.5% only but going by the GDP of the total industrial sector it contributes around 10% to 11%. Even mining done on small scale contributes 6% to the entire cost of mineral production.

metals and mining sector in India. India has a vast mineral potential with mining leases granted for longer durations of 20 to 30 years. India holds a fair advantage in cost of production and conversion costs in steel and aluminum. The country is the third largest steel producer with a production of 97.38 million tons of crude steel in FY17.

3 Metals and Mining For updated information, please visit India ranks 4th globally in terms of iron ore production. In FY17, production was expected to reach 175.51 million tonnes of iron ore. India has around 8 per cent of world's deposit of iron ore

This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations. All costs listed are in 2012 US$.
