Rotary furnace stir frying of aluminum ash involves adding aluminum ash and solvent to an iron pot and manually stir frying it through heating and its own heat. After stir frying, it is collected at the bottom of the pot. The tilting rotary furnace treatment method involves adding a small amount of salt flux or no salt flux to the tilting rotary furnace to melt aluminum. Mix aluminum ash and molten salt in a rotary kiln, rotate and heat at high temperature to melt and settle the metal aluminum at the furnace bottom, achieving separation. This method is simple to operate and easy to implement
