After the first reaction in hemihydrate mode, the resulting acid is separated. It has a low sulfate content and contains 46% P 2 O 5.Once it has been washed, the remaining alpha hemihydrate is mixed with the sulfuric acid, under conditions in which the alpha hemihydrate is unstable and recrystallized like gypsum, producing a co-crystallized and unattacked gypsum with a low P 2 O 5 content.
