(A) an aluminum scrap and a flux are charged into a vortex formed in an aluminum molten metal to dissolve the aluminum scrap in the aluminum molten metal, and the inclusions contained in the molten aluminum The black dross formed by capturing the flux is repeatedly lowered and floated in the molten aluminum through the vortex to form spherical black dross aggregated in a spherical shape; (B) crushing and pulverizing the spherical black droplets to divide them into aluminum particles and droplet particle powders; (C) decomposing the dross particulate powder into water with water to decompose the hydrolysis gas, the soluble solid and the insoluble solid into water; And (D) treating at least one of the aluminum particles, the hydrolysis gas, the soluble solid, and the insoluble solid material so as to be recyclable. |
