Review on Extraction and Separation of Gallium from Solution

Recovering gallium from intermediate material produced in iron and steel, non-ferrous metals, coal chemical industry and phosphorous chemical industry exists the problem that extracting gallium from solution containing variety of metal ions. The present status of studies on extraction and separation of gallium from the solution are reviewed in this work. The key factors influencing separating gallium from other metal ions in the solution by the solvent extraction, liquid membrane extraction, extraction leaching resin extraction process are analyzed and discussed. The new research trend for recovery gallium from solution versatile different metal ions contained is proposed. Solvent extraction, liquid membrane extraction and extraction leaching resin are able to effectively extract gallium from solution. Synergistic extraction, liquid membrane extraction and extraction leaching resin extraction are prominent and prospective in future, owing to their high performance of selectivity and extraction rate, short process, environmental friendliness and good application prospect.
