Rampura Agucha is stratiform, sediment-hosted, high grade zinc & lead deposit. The ore body is massive and lens shaped with consistent ore grade.

The massive Pb-Zn sulfide deposit at Rampura-Agucha area found in the Mesoproterozoic meta-sedimentary rocks in the district Bhilwara, Rajasthan, which belongs to the Bhilwara supracrustal belt of Aravalli-Delhi orogen (Deb and Sarkar,1990). The geology of this significant deposit was first studied by the Gandhi et. al. (1984). According to Deb et al (1989), the stratigraphic status of the ore body was assessed based on the Pb-Pb model age of about 1.8 Ga. This deposit is situated around 220 km away in the south west direction from the state capital, Jaipur. The area is famous for its largest Pb-Zn deposit and also one of the lowest cost producers of Zn globally, where the ore body is reaching out over a length of about 1.55 km with a normal width of 60 m while at places the width increases and goes up to 100 m. The estimated Pb-Zn ore reserve in the study area is around 63.65 million tonnes with an average content of Zn-13.38%, Pb-1.9% and Fe-9.58% (Gandhi et. al., 1984).

The main ore body is approximately 1.5 kilometres long and has a width ranging from five metres to 120 metres with an average of approximately 58 metres. It extends from the surface with recent exploration intersecting up to 15 metre wide mineralised zones at depths of over 900 metres. The southern boundary of the ore body is sharp and steeply dipping while the northern margin is characterised by a thinning mineralised zone. Grades remain relatively consistent with depth. The ore body consists of sphalerite and galena, with localised concentrations of pyrite, arsenopyrite, pyrrhotite and tetrahedrite-tennantite.

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.

Rampura Agucha open pit mine, which was commissioned on March 25 1991, delivered its final ore on March 25 2018.

The development of North Decline (ND1) was completed at Rampura Agucha (RA) mine. This improves the accessibility of shaft section, alternate emergency evacuation, ease in mine equipment deployment at lower mine levels, face charging with emulsion explosives, face drilling with long feed jumbo, and so on.

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 stored in specially constructed tailing dam, which is considered as the most compatible on-site storage facility for long term disposal of tailings. The base of the tailing dam is fully sealed by the application of a layer of impervious soil at bottom. After settling, the tailings water gets recycled t ........
