Reaction Steps
In Reaction 1a, the phosphate rock is first reacted with phosphoric acid to produce monobasic calcium phosphate (monocal) slurry. Then, in Reaction 1b, the monobasic calcium phosphate slurry is reacted with sulfuric acid to produce phosphoric acid and calcium sulfate dihydrate (gypsum). Filtration is used to separate gypsum.
