Process for separating trivalent iron from an aqueous chloride solution |
| abstract |
A process for separating trivalent iron from an aqueous chloride solution comprising contacting the aqueous solution with an organic phase containing an organophosphoric compound as an extracting agent for trivalent iron and at least 40 percent in volume of a long chain aliphatic alcohol, separating the iron-loaded organic phase from the aqueous solution, and re-extractng the iron from the iron-loaded organic phase by contacting the latter with water or acidulated water so as to produce an aqueous iron chloride solution. n Owing to the high alcohol content of the organic phase, iron can be re-extracted with a small amount of water. |
