A method of concentrating and purifying phosphoric acid obtained by wet process and other types of impure phosphoric acid comprising heating the acid by direct contact with combustion products so that a substantial proportion of P2O5 is distilled from the acid, which is condensed with water to forming an aerosol in the combustion products, removing the aerosol from the residual acid and causing the aerosol particles to group together to form liquid produced acid.
