HZL Approves Rampura Agucha Tailings Reprocessing Plant to Support Doubling of Capacity

On August 18, Hindustan Zinc Ltd (HZL) announced that its Board has approved the establishment of India’s first zinc tailings reprocessing plant at Rampura Agucha, Rajasthan. The facility will have a designed capacity of 10 Mtpa and an investment of ₹3,823 crore, targeting completion within 28 months from the start date. The plant will recover valuable metals such as zinc and silver from tailings, marking a key step in the company’s strategy to double production capacity, enhance resource efficiency, and promote the circular economy.

Earlier in June 2025, HZL approved the first phase of expansion at Debari, involving a new 250 ktpa integrated smelter and related mine and concentrator expansions. This project, scheduled for completion in 36 months, is expected to lift total zinc and lead capacity from the current ~1.13 Mtpa to more than 2 Mtpa, while raising silver output to up to 1,500 tonnes per year.
