Abstract
A molecule enabling the selective recovery of gold, platinum, and palladium from an oxidative organic solution that also contains contaminants such as base metals, polymers, or other gangue material. The disclosed formula simultaneously eliminates multiple costly and hazardous steps of recovering such metals by using a single chemical comminution and solvent extraction process using dual organic phases. The resulting gold, platinum, and/or palladium-containing solution can be stripped to recover these elements and to regenerate the extractant for subsequent use.
