MUMBAI, India, Dec. 13 -- Intellectual Property India has published a patent application (202511102724 A) filed by Indian Institute Of Technology, Kanpur, Uttar Pradesh, on Oct. 24, for 'a process of preparing sacrificial zinc anode from secondary dross, and uses thereof.'

Inventor(s) include Chahar, Bharat Singh; Singh, Vikas; and Mondal, Kallol.

The application for the patent was published on Dec. 12, under issue no. 50/2025.

According to the abstract released by the Intellectual Property India: "The present invention relates to a process for recovering zinc from secondary dross generated in galvanizing operations and converting it into value-added products. The process involves cutting and cleaning secondary zinc dross, followed by sequential melting and casting to produce refined sacrificial zinc anodes. The sacrificial anodes exhibit controlled grain size, defined electrochemical properties, and suitability for further processing. The recovered anodes are further utilized to produce zinc sulfate heptahydrate, high-purity zinc powder, and zinc-coated articles via electrochemical methods. The invention provides efficient recovery of zinc from secondary dross, enabling the production of multiple industrially useful zinc products with desirable microstructural and electrochemical characteristics."
