SnapshotRampura Agucha Mine (RAM) is the world’s largest underground zinc producing mine and has the richest zinc-lead deposit in India.

In 2025, Hindustan Zinc commissioned a 4,000 KLD water treatment plant to enable effective utilisation of recycled water and reduce freshwater consumption, and completed the transition from wet to dry tailings disposal at Rampura Agucha.

The shaft hoisting capacity at RAM showed a marked improvement, driven by multiple debottlenecking and digitalisation initiatives. Efforts to further augment the capacity to 12,000 tpd are ongoing.

Deposit type

  • Sediment-hosted

Summary:

Rampura Agucha is a stratiform, sediment-hosted Lead Zinc deposit, occurs in Pre-Cambrian Banded Gneissic Complex and forms a part of Mangalwar complex of Bhilwara geological cycle (3.2-2.5 billion years) of Archean age and comprising of magmatites, gneisses, graphite mica schist, pegmatite and impure marble. The rocks have been subjected to polyphase deformations and high-grade metamorphism. The deposit lies in the contact zone of Mangalwar - Sandmata complex and along the major NE trending Delwara lineament and predominantly covers southeast plain of Ajmer and Bhilwara.

The deposit has been broadly domained into four discrete zones, referred to as; ‘south ore’ (zone 1); ‘core ore’ (zone 2); and ‘north ore’ (zones 3 and 4). The basis of the zones is the reasonably distinct variations in the zinc grades along strike. Furthermore, the relationship between lead and silver between the northern and southern zones shows a markedly different regression profile.

The graphite-mica-sillimanite schist hosts the economic mineralization in the Rampura Agucha deposit. The economic minerals in order of decreasing abundance along with their ranges are:
• Sphalerite (15-20%)
• Pyrite (15-18%)
• Pyrrhotite (12-14%)
• Galena (1-2%)
• Sulphosalts (0.1-0.2%)

The deposit extends over 1,550 m along strike and has now been intersected to a vertical depth of 1,100 m below surface. The horizontal thickness varies between a few metres to 80 m, averaging between 50 to 60 m in the upper 250 m of the deposit. The mineralised unit also contains some inclusions of sub-ore grade material. The average dip shallows from around 70- 80° in the upper part of the deposit to about 50° in the middle and lower portions, as well as the northeast and southwest flanks. Deep drilling has shown that the deposit thickens and steepens back to approximately 70° in the lower portions, while the strike length at these lower portions appears to remain restricted to around 500 m.

Two different main ore types are identified at RAM from the North and South areas of the deposit. The material from the North area is understood to be softer and more difficult to float, while material from the South area is harder and contains higher levels of graphite.
