HZL to Recover Zinc and Silver from Mining Waste in Rajasthan
Hindustan Zinc Limited (HZL) plans to build a plant in Rajasthan to get zinc and silver from old mining waste.
This waste is called tailings, and it still has valuable metals.
This plant is the first of its kind in India and aims to make use of materials that were previously thrown away.
Recovering these metals can help India import fewer materials, especially those crucial for clean energy.
Experts believe this can help India become self-reliant in critical minerals.
It's like finding new resources in the old trash and making better use of them.
HZL will build a plant to recover zinc and silver from mining waste.
The plant will be in Rampura Agucha, Rajasthan and will process 10 million tonnes annually.
The project aims to reduce India's dependence on imports of critical minerals.
Experts believe recovering minerals from waste can extend the life of mines.
The project costs ₹3,823 crore and seeks to create a national resource.
