Hindustan Zinc Limited has signed a memorandum of understanding (MoU) with Virginia Tech to conduct research aimed at improving silver recovery across its lead–zinc (Pb–Zn) concentrators. The collaboration will focus on scientific studies to refine flotation methods and optimise the use of reagents used in mineral processing operations.
According to a press release issued by Hindustan Zinc Limited, the research will analyse metallurgical factors influencing flotation selectivity and overall metal recovery in concentrator plants. The project will examine reagent–mineral–water interactions that affect process stability and concentrate quality, considering both current plant configurations and variability expected in future ore types.
The partnership will also work toward defining optimised operating approaches and reagent regimes intended to improve process stability, concentrate quality, and operational consistency. The study will include diagnostics, laboratory evaluations, and technical assessments designed to support implementation across operations.
“At Hindustan Zinc, we believe the next phase of growth in the metals and mining sector will be powered by science, innovation, and collaboration. Our partnership with Virginia Tech represents an important step in strengthening our knowledge ecosystem and preparing our operations for the future. By working with leading global institutions, we continue to build capabilities that will define the next generation of mining excellence,” said Arun Misra, Chief Executive Officer of Hindustan Zinc.
Aaron Noble, head of the Department of Mining and Minerals Engineering at Virginia Tech, said the collaboration would apply academic research to industry challenges. “By working directly with industry, we can apply our cutting-edge research on mineral recovery to real operational challenges and opportunities. This ensures our discoveries go beyond advancing knowledge. We’re translating this research into more efficient resource use, stronger supply chains, and tangible benefits for the broader mining sector,” Noble stated.
The collaboration will also include workshops, training sessions, and technical exchanges aimed at supporting knowledge transfer and technical capacity building for Hindustan Zinc’s operational teams.
Hindustan Zinc Limited, a Vedanta Group company, produces zinc, lead, and silver and supplies metals to customers in more than 40 countries. The company operates mining and processing facilities in India.
