Zusammenfassung:	A method for obtaining complex mineral fertilizers consists in that phosphate raw material is mixed with 70 % sulphate acid, loaded to chamber, kept with heating during 60-90 minutes. Before delivery to chamber 70 % sulphate acid is mixed with potassium sulphate or hydrsulphate at a molar ratio of K+:SO42- = 0.5-2:1, then phosphate raw material and sulphate acid solution are heated to the temperature of 100-130 DEGREE , at that molar ratio of SO42-: (CaO+MgO)=1:1.4-1.5.
