The Rampura Agucha Mine (RAM) is an ISO 9001, ISO 14001, ISO 45001, ISO 50001 and SA-8000 certified underground zinc and lead mine. Located in the Bhilwara district of Rajasthan state, RAM is the largest and richest, lead-zinc deposit in the country and among the world’s largest with 75.0 Mt of ore reserves and resources (R&R) with in situ average grade of 10.8% zinc and 2.0% lead on an exclusive basis as on end of FY 2021-22. It is also one of the lowest cost zinc producing mine globally. The mine is equipped with best-in-class infrastructure, operates at high levels of ESG standards, deploys advanced technology for mining activities for better targeting and has some of the best people in the mine’s leadership, with extensive community outreach.
The Rampura Agucha Mine continued to scale its operations with focussed interventions on operational and technology fronts and new targeted initiatives that led to a 5.6% year-on-year increase in ore production and 10.4% increase in mined metal production over the previous fiscal. RAM is currently producing at 4.5 Mtpa through its underground operations. It is in the process of building infrastructure to support its expansion plan to enhance ore production beyond 4.5 Mtpa.
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.
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.
