Rampura Agucha is a zinc and lead mine located on a massive sulfide deposit in the Bhilwara district of Rajasthan, India.[1] [2] Rampura Agucha is located 220 km from Jaipur. It is north of Bhilwara, and northwest of Shahpura. Rampura Agucha is 17 km southeast of Bijainagar on NH 79.[1] The mine is owned by Hindustan Zinc Limited (HZL), and has the world's largest deposits of zinc and lead.[1]
History
editRampura Agucha deposits were discovered in August, 1977 by T. C. Rampuria, a geologist with the Government of Rajasthan's Directorate of Mines and Geology. Hindustan Zinc Limited started drilling in February, 1980 and a report regarding the estimate of the deposit was submitted in 1981.[3] The development of this mine started in 1988 and the first ore production was in March 1991. Rampura-Agucha has a combination of open pit mine and underground mine
Geology
editRampura Agucha is a zinc-lead sulfide deposit that is located in the Bhilwara belt which is part of the Aravalli-Delhi orogen.[4][5] The Bhilwara belt is mostly comprised of metasedimentary, metamorphosed dolomite and a small amount of igneous rocks.[5][6] The deposit was originally a sedex deposit before experiencing a metamorphic event.[2]The high grade metamorphic event is theorized to have occurred approximately 1 billion years ago.[4][6]
Smelter for this mine
editChanderiya smelter complex was built in the Chittorgarh district to refine the zinc-lead ore of this mine.[7]
Rampura Agucha is today the world's largest zinc producing mine.
