Abstract

Process for the preparation of K2SO4 from potassium chloride salts, calcium sulphate salts and another sulphate source, in which syngenite is formed and then decomposed. In one embodiment, syngenite is decomposed to prepare crystalline K3H(SO4)2. The K3H(SO4)2 crystals are recrystallised to prepare K2SO4 crystals. In another embodiment, syngenite is decomposed in order to prepare KNO3 in solution and solid CaSO4. The solution containing the KNO3 is separated from the CaSO4 precipitate and subjected to a crystallisation step, whereupon the solid, crystalline KNO3 is obtained.
