Rampura- Agucha zinc mine
In 2016, Rampura Agucha is expected to be the world's largest zinc producer, and has held this position since 2008. The project was given the go-ahead by the Indian Government in 1985. Commercial production started in June 1991. Until recently, mine production has come solely from the Agucha open pit. The high average head grade of the ore milled helped make this the largest zinc mine in the world for a number of years, with contained metal production averaging 650kt/a zinc between 2009 and 2014. Ore from underground stopes began supplementing the open pit ore feed to the mill from 2013, with some development ore prior to this.
