Abstract

Process for the purification of phosphoric acid by wet process which consists, after transformation into cations, of eventual reduction of the impurities constituted by elements present in their higher oxidation state in the form of anionic complex in successively: 1.1 - an extraction of phosphoric acid by a solvent of this product to separate the cationic impurities. 1.2 - an extraction of the anionic impurities of the phosphoric acid thus obtained by means of a solvent not soluble in aqueous medium.
