His work focuses on the direct recovery of precious metals, particularly gold and platinum group metals, using advanced solvent extraction techniques.
Latest Patents
Pouskouleli holds a patent for the direct recovery of precious metals by solvent extraction and selective stripping/precipitation. This innovative method allows for the efficient extraction of gold and other precious metals from chloride solutions. The process utilizes substituted quinolines, specifically alkyl substituted 8-hydroxyquinoline, as active extractants. Gold can be precipitated using hot water or hydrogen after a cold water wash, while palladium remains in the organic phase and is precipitated through more severe hydrogen reduction or stripped with acid. Platinum and other precious metals can be stripped into water and recovered through hydrogen reduction in stages. The organic phase remains stable and can be recycled, provided that acid is washed out before any hydrogen reduction.
