ABSTRACT:
Iron containing aqueous, acidic solutions, such as acidic stripping solutions used to remove iron from organic extractants, are purified by subjecting the acidic solution to a hydrothermal treatment at elevated temperatures and pressures which cause the precipitation of the dissolved iron in easily separable form. The hydrothermal treatment is accomplished at temperatures in excess of about 100.degree. C. The process can be applied to acidic solutions containing the dissolved iron in the form of ferric sulfate, ferric nitrate or chloride and is particularly adaptable to acidic stripping solutions resulting from the purification of organic extractants employed to extract iron impurities from solutions obtained in the acid leaching of clays, ores and concentrates.
