Abstract
A process for obtaining detergent grade phosphoric acid from a wet route phosphoric acid solution obtained by acidification of uncalcined mineral phosphate, comprising adding to said solution approximately 1 to at least 2% by weight of activated silica and about 0.01% to 0.1% by weight of coagulant, decant the resulting mixture into a solid phase and a liquid phase of phosphoric acid substantially free of solids, separate the liquid phase of phosphoric acid from said solid phase, evaporate said acid phosphoric acid at a P2O5 concentration of at least 54%, subject the concentrated phosphoric acid to solvent extraction with a phosphoric acid selective solvent and remove the solvent from the phosphoric acid to recover detergent grade phosphoric acid.
