文摘The extraction of phosphoric acid from leaching solution of phosphate rock with hydrochloric acid has been studied.The extraction ratio of phosphoric acid can be as high as 80% when a new synergetic system of cyclohaxanone∶isopentanol=6∶4( V/V ) is used by a three stage countercurrent process.The stripping product has very low contents of fluorine and chlorine,yet no detectable calcium.
