Abstract
The present application provides a method for separating and purifying phosphoric acid and phosphogypsum from a wet-process phosphoric acid slurry, and phosphoric acid and phosphogypsum prepared thereby. The method is beneficial for the dissociation, precipitation and separation of colloidal silicon and carbon impurities, such that the aim of in-situ removal and rapid separation of colloidal impurities to obtain the ore slurry, from which impurities have been removed, during a reaction process for outputting phosphogypsum is realized, and a low-impurity phosphoric acid product and phosphogypsum product can be obtained after the ore slurry, from which impurities have been removed, has been further treated.
