System and method for aluminium black dross recycling

The present invention, aluminum as black de about Los recycling method, (A) the inclusions containing aluminum scrap and a flux charged into the vortex formed in the molten aluminum, dissolving the aluminum scrap in the molten aluminum, and the aluminum molten metal step of repeatedly lowering and injuries in the molten aluminum to form a spherical black dross concentrate in the black rectangle draw Suga through the vortex black dross formed are trapped in the flux; (B) dividing the aluminum grains and a dross powder particles by crushing and grinding the spherical black dross; (C) the step of decomposing water for the dross powder particles by water and the water splitting reaction in the hydrolysis gas, and soluble solids and the insoluble solids; And (D) a step of processing to be recycled to the aluminum particles, the hydrolysis gas, the soluble solids and at least one of the water-insoluble solids; includes.
