The Rampura Agucha mine is in Rajasthan, in the northwest of India, and is the world’s largest zinc producing mine. Reserves and resources of Rampura Agucha as of March 31, 2013, were about 109 million tonnes with a best-in-class zinc-lead reserves grade of 15.4%.

At present the Rampura Agucha mine is annually producing 6.15 million tonnes of ore from the open-pit mining operation and is treating the same in a beneficiation plant.

With the present system of mining method (open-pit), the mine will be operative up to a level that is 372 metres below the surface. Beyond this level the mineral reserves and resources are to be extracted by suitable underground mining methods.
