Abstract:

Gallium(Ga) is widely used in semiconductor, catalysis, medical and other fields. With the vigorous development of the semiconductor industry, the increasing demand for Ga has prompted people to find new sources. Recycling Ga from coal fly ash can not only reduce environmental pollution, but also alleviate the growing demand for Ga. This review summarized the Ga occurrence in coal fly ash, leaching process and separation methods of Ga from coal fly ash. Meantime, this paper highlighted the current research status of solvent extraction and adsorption for the recovery of Ga from coal fly ash. The existing problems were discussed. Finally, the recovery of Ga resources from coal fly ash was prospected and the synergetic recovery of Ga and other multi elements from coal fly ash had been proposed.

Key words: gallium, coal fly ash, recovery, occurrence, leaching, separation
