The invention relates to a recycling and clean production method for preparing yellow phosphorus, sylvite, aluminum oxide, molecular sieves, slag cement and architectural profiles through potassium-bearing phosphorite. The method utilizes two routes, for the first route, high quality yellow phosphorus is produced by the potassium-bearing phosphorite and coke nuts through an electrothermal method, water quenching is conducted on yellow phosphorus slags, KAlO2 is dissolved out, filtration is conducted, CO2 is introduced, Al(OH)3 is settled, first filtrate is obtained, and the Al(OH)3 is converted through temperature control to obtain Al2O3. For the second route, orthoclase power and Na2CO3 are evenly mixed, roasting is conducted through yellow phosphorus tail gas, water leaching is conducted through water, the CO2 is introduced to settle out silicon-aluminum colloid, and second filtrate is obtained. Crystallization and drying are conducted on the first filtrate and the second filtrate, and K2CO3 and Na2CO3 are obtained. The Na2CO3 returns to the second route to be recycled. The content of K2O, Na2O, SiO2 and Al2O3 is adjusted for partial silicon-aluminum colloid which is not subjected to sedimentation and the filtrate, hydrothermal crystallization reaction is conducted, and the molecular sieves are obtained; settled silicon-aluminum colloid is mixed with the yellow phosphorus slags to prepare the slag cement and/or the architectural profiles.
