Background Information

Rajpura Dariba Mine is an underground mine, commissioned in 1983. It is located about 75 kilometres north-east of Udaipur, in the state of Rajasthan in India and is well connected with roads.

Process Description


Mining is carried out using the Blast Hole Stoping method with mined out stopes backfilled with cemented tailings.


The ore is crushed underground before being hoisted to the surface. It is then crushed again and milled before undergoing a flotation process, to produce the concentrate.

Zinc and Lead concentrates produced are transferred to our smelters.
