| Abstract: | A new hydrometallurgical technique has been developed to recover indium from wastewater by solvent extraction. This technique involves steps of reducing purification, TBP solvent extraction, selective back extraction, further purification by di (2 ethyl hexyl) phosphate (P 204 ) extraction and back extraction with HCl, replacement of indium by zinc plate and smelting. The qualified raw indium product with mass fraction of indium > 98.5% can be obtained by this technique. The total recovery of indium is > 90%. |

| Keywords: | indium extraction separation tributyl phosphate (TBP) di (2 ethyl hexyl) phosphate (P 204 ) |
