Recovery of Rare Earth and Critical Metals from Unconventional Sources

“…In the February 2022 special topic on ''Technology Metals in the Circular Economy of Cities'', JOM advisors of the Recycling and Environmental Technologies, Process Technology and Modeling, and Energy technical committees of TMS (The Minerals, Metals & Materials Society) presented a collection of manuscripts focusing on the recovery of technology metals-including strategic metals-from municipal waste streams. 3 To build on that, this special topic invited original research and reviews discussing the sustainable extraction, processing, and separation of rare earths and other co-product metals from unconventional sources. The papers presented provide updates on advances in critical materials separations science and engineering, metals processing, and process optimization and intensification relevant to unconventional resource recovery.…”
