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.
Newmont's mission is to build a sustainable mining business while leading in safety, environmental stewardship and social responsibility. Today, we primarily mine gold and copper, as well as silver and other metals and minerals.
Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores.
