Rajpura Dariba
Overview:
Rajpura Dariba (RD) Mine is one of our earliest ventures, operating underground via decline, main shaft, and auxiliary shaft. We are actively working to enhance production to 4.0 Mtpa with the current reserve of 51.3 Mt and total Reserves & Resources of 90.3 Mt. This augmentation is planned to be achieved through a new Portal and Decline of larger cross-section for the East Lode Mining, along with advanced mechanization and automation.
With a dedicated focus on boosting the production capacity, Rajpura Dariba Mine’s numerous production centres invest in elevating efficiency, productivity, and safety via strategic automation and mechanization initiatives.

Background Information
Commissioned in 1983, Rajpura Dariba Mine is an underground operation situated 75 km northeast of Udaipur, Rajasthan. Its strong road connectivity adds to its strategic location.
Process Description
Exploration:
By introducing cutting edge technology in exploration Rajpura Dariba Mine has enhanced and establish our Reserves & Resources base of 90.3 Mt.
Mining:
Mining is carried out using the Long Hole Stoping Method with backfilling by Paste & Hydro Filling; Ore transportation through Skip hoisting and LHD-LPDT combination.
Processing:
A new mill of 1.1 Mtpa capacity has been commissioned. 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.
Along with the processing plant, a 550 TPH capacity Paste fill & Dry-Tailing Plant is also commissioned at RD Mine enhancing the Safety, Mineral & Water Conservation, a step towards our ESG journey.
Technology:
Advanced technology APC & MSA controlled beneficiation process. Real time ground monitoring by geotechnical instruments including EPC, Multi-point bore hole extenso-meters and Vibrating Wire Stress Meter. Use of Blast Hole Survey & Cavity Monitoring System to conserve the mineral. Leaky feader network for effective communication in underground operations. Automation and real time monitoring of the compressors & main Mechanical Ventilators from Mine Control Room for energy conservation, to reduce carbon footprint in our ESG journey.
