ABSTRACT:
An improved method for producing wet process phosphoric acid with low post-precipitation characteristics from an unclarified dilute wet process phosphoric feed acid is described. The feed acid is processed through crystallization, centrifugation and concentration steps under controlled conditions to produce the desired products. The method also allows for the simultaneous production of merchant grade phosphoric acid and clarified merchant phosphoric acid.
