Abstract
Ferric iron is separated from aqueous solutions containing it in a concentration of not more than 4g./l. and other metal values by contacting the aqueous solution, at a pH not less than 0.5 of a pH unit below the pH of hydrolysis of the iron salt in solution, with a solution in an organic solvent of one or more saturated aliphatic monocarboxylic acids having from 8 to 11 carbon atoms and separating the aqueous and organic phases obtained. At higher initial Fe3+ concentrations, say 20 g./l., it is necessary to reduce the iron concentration by conventional methods, e.g. precipitation with alkali, before applying the process of the invention. The pH of the aqueous solution is adjusted with alkali immediately before extraction. The raffinate may be extracted repeatedly and the iron-loaded organic phase may be contacted with dilute acid, e.g. H2SO4 to regenerate the organic reagent which is then recycled. Specified acids are 2-ethyl hexanoic acid, pelargonic acid and Versatic acid, Versatic is a Registered Trade Mark, a mixture containing a ,a 1-dialkyl propionic acids, for which kerosene is a suitable solvent. Comparatively high quantities of iron may be removed from solutions also containing Cu and Ni by precipitating Fe(OH)3, substantially free of Cu and Ni at pH 2.5 and removing the remaining iron by extraction.
