Background Information

Rampura Agucha was commissioned in 1991 as an opencast mine. It is located 230 km north of Udaipur, in the State of Rajasthan in India. Rampura Agucha is stratiform, sediment-hosted, high grade zinc & lead deposit. The ore body is massive and lens shaped with consistent ore grade.

Process Description


The mine is highly mechanized with state of the art technology. Underground Mining is carried out using Long Hole Open Stoping with Paste Fill method with mined out stopes backfilled with cemented rock & with cemented tailing in paste form.


Processing facilities use rod mill – ball mill combination in stream I; Semi-Autogenous Grinding (SAG) mill – ball mill combination in stream II, III & IV; and flotation methods to produce zinc and lead concentrates. The concentrator is equipped with the state-of-art-automation, which includes the Experion process control system; Multi stream analyzer to ensure faster & accurate readings of different metal percentages in the various streams and Froth image analyzer that provides actual image of froth bubbles to facilitate effective quality control.

Zinc and lead concentrates produced at Rampura Agucha are transferred to our smelters. The tailing generated due to beneficiation of ore are used by paste filling plants.
