Hindustan Zinc signs MoU with Virginia Tech to boost silver recovery

Hindustan Zinc Limited has signed a memorandum of understanding (MoU) with Virginia Tech to advance research aimed at improving silver recovery across its lead–zinc concentrator operations.

In an exchange filing on Thursday, March 5, the company said the collaboration will focus on scientific studies to refine flotation methods a mineral processing technique used to separate and concentrate valuable metals from mined ore and optimise the use of reagents, specialised chemicals used during mineral processing.

The initiative is expected to help improve concentrate quality and enhance operational efficiency at Hindustan Zinc’s processing plants.


Under the partnership, researchers at Virginia Tech will work with Hindustan Zinc to examine metallurgical factors that influence flotation selectivity and metal recovery. The study will particularly analyse interactions between reagents, minerals and water that affect process stability and concentrate quality.

Virginia Tech, a public research university based in Blacksburg, Virginia, is widely recognised for its research in mining engineering, mineral processing and metallurgical sciences.
