Abstract. The possibility of adding an aluminium black dross leached residue (BDLR), mainly consisted of spinel (Al 2 MgO 4) and corundum (Al 2 O 3), in the raw meal for the production of Portland cement clinker was investigated.This leached residue was obtained during the hydrothermal treatment of an aluminium black dross, formed during aluminium scrap melting.
