text: A process for removing iron and arsenic from crude phosphoric acid, which comprises charging said crude phosphoric acid with hydrochloric acid, mixing weakly basic liquid anion exchanger with the resultant mixture, separating the weakly basic liquid anion exchanger containing substantially all the iron impurity and part of the arsenic impurity from the partially purified phosphoric acid mixture, and concentrating said partially purified phos phoric acid mixture by evaporation, thereby removing substantially all the hydrochloric acid and remaining arsenic by evaporation to produce concentrated phosphoric acid.
