Brief description of the recovery of gallium by liquid / liquid extraction from solutions of zinc

摘要

The present invention relates to a process for recovering gallium by using a liquid/liquid extraction process. It relates more particularly to a liquid/liquid extraction process for gallium present in acidic aqueous solutions containing especially zinc, consisting in bringing the aqueous solution into contact with an organic phase containing chiefly an organic solvent and an extractant, characterised in that the extractant is a or a mixture of compounds belonging to the class of substituted hydroxyquinolines and in that the organic phase also contains a surface-active agent of ionic nature and a coagent for the said surfactant. The process permits an industrial extraction of the gallium in acidic solutions containing zinc.
