Electra Battery Materials Corp. has appointed Dr. George Puvvada, PhD, PEng, PMP, as vice-president of metallurgy and technology, effective today. Dr. Puvvada brings 30 years of experience developing effective flowsheets for recovering metals from complex formations and completing large-scale projects with some of the mining industry's largest companies, including Cameco, Xstrata, Vale and Inco.

Dr. Puvvada joined Electra in 2020 as technical manager and led the development of the company's flowsheets for producing battery-grade cobalt sulphate and recycling black mass material to recover high-value elements, including nickel, cobalt, lithium, copper and manganese. Dr. Puvvada guided Electra's efforts to produce high-quality nickel, cobalt and lithium carbonate products from North America's only plant-scale battery materials recycling trial to date.

"George's promotion to vice-president, metallurgy and technology, is a testament to his dedication, hard work and the success we have achieved with our black mass recycling trial," said Trent Mell, Electra's chief executive officer. "As a member of the senior leadership team, George brings invaluable industry experience and subject matter expertise as we pursue our strategy of becoming the leading North American refinery of electric vehicle battery materials."

Prior to joining Electra, Dr. Puvvada was employed with Northern Sun Mining, overseeing all aspects of feed evaluation, metallurgical processing, lab supervision and project development. He also previously worked as a metallurgist at the Peko mine in Australia, testing, developing and piloting for the recovery of base and precious metals. Dr. Puvvada has also worked with some of the world's leading metallurgical and engineering firms, including SNC Lavalin, Tetra Tech, Ortech and SGS.
