Description

Novel Critical Metals Recovery Techniques from Coal Ash Authors Mr. Claudio Arato - Canada - SonoAsh Abstract Abstract Summary This presentation will focus on the new and emerging areas of interest for SonoAsh. While Critical metals recovery has always been part of the SonoAsh process, this presentation will specifically focus on our new, patent pending methodology to extract Lithium ions from coal ash using a proprietary membrane grafting techniques developed in collaboration with Dr. Mohamad Al-Sheikhly’s at the University of Maryland, College Park. The technology is in the state of optimization and studies are being performed to determine the maximum extraction capacities of these membranes. Furthermore, striping methodologies are currently being developed to determine how the extracted Lithium can be further recovered from the membranes. The selective nature of the membrane assembly through innovative surface coordination chemistry techniques for Lithium separation demonstrates a bespoke pathway to more efficient singular Lithium recovery strategies and the potential for an additional business opportunity for the coal ash industry. From the development program to date, eight unique polymer membranes have been developed using an electron beam direct grafting method requiring irradiation by a linear accelerator at the National Institute for Science and Technology (NIST) in Bethesda, MD, with the specific goal of capturing and separating Lithium salts more selectively. This program was informed by the results and knowledge obtained from a previous membrane development program for the unique recovery of Uranium from sea water. Results are expected to be complete and available for presentation during WOCA 2024.
