Abstract	This study wa attempted to extract the Potash-Ammonia Fertilyzer in most satisfactory yield from the Uncalcinecl Domestic Alunite ore applying an optimal reaction conditions (Ammonia water concentration and applicable reaction pressure, etc.), it was found that almost all amount of K2SO4 was extracted in the forms of K2SO4·(NH4)2SO4mixture under such conditions. The experimental data to note are as follows: 1. The optimal pressure applied to the reaction was 600 to 700 Psig. 2. The optimal concentration of Ammonia water was 7 Mol/L. 3. The reaction time needed was 3 hours. 4. The extraction rate and degree were not at variance with sorts and occurrences of Alunite ore.
