Synergistic extraction of critical metals from the oxalic leachate of spent FCC catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study introduces an improved hydrometallurgy process utilizing a synergistic approach to improve metal recovery from secondary sources of critical metals. It provides a more efficient alternative to traditional single‐extractant methods for separating critical metals from spent refinery catalysts.
