The invention provides a method for preparing potassium sulphate and potassium sodium composite feldspar from potassium feldspar in a mirabilite way. The method comprises the following steps in sequence: crushing potassium feldspar and mirabilite as the raw materials; mixing; carrying out molten-salt reaction; dipping in water; filtering; evaporating the filtrate; crystallizing; and separating. The method is characterized in that the molten-salt reaction comprises the processes of uniformly mixing potassium feldspar powder which is sieved by at least 100 meshes with the mirabilite powder which is sieved by at least 50 meshes based on the mass ratio of 1: 0.5 to 5; and reacting for 0.5 to 3 hours at 850 to 1200 DEG C, wherein the sum of K2O and Na2O in the potassium-sodium composite feldspar is not less than 10%, and the ratio of K to Na is 1: 1 to 30. Potassium sulphate is high-quality chloride-free potash fertilizer; and the potassium-sodium composite feldspar is a necessary high-quality ...
