| titleOfInvention | Process for the separation of indium from metal-containing, aqueous solutions |
| abstract | The invention relates to a process for the separation of indium (III) ions from metal-containing, aqueous solutions containing In (III) compounds with the steps a) extraction of the aqueous, metal-containing solution with an organic solution containing an organic solvent and an organophosphorus extractant, the volume ratio aqueous / organic solution being greater than 1, b) extraction of the metal-containing organic solution resulting from a) with a neutral or acidic aqueous solution, c) extraction of the metal-containing organic solution resulting from b) with an acidic, aqueous solution containing chloride ions, d) extraction of the aqueous solution resulting from c) with an organic solution comprising an organophosphorus extractant, the volume ratio aqueous / organic solution being greater than 1, e) extraction of the organic solution resulting from d) with an acidic aqueous solution containing nitrate ions, wherein indium passes into the aqueous solution, f) diffusion dialysis of the aqueous solution resulting from e) to remove the acid anions, g) adding a base to the aqueous solution resulting from f) and precipitating the indium as indium hydroxide, wherein Fe (III) ions contained in the aqueous, metal-containing solution are first reduced to Fe (II) ions before step a), wherein before step e) an extraction of the d) resulting organic solution with water or an acidic aqueous solution containing acid anions selected from phosphate ions and / or sulfate ions, wherein indium remains in the organic solution. |
