Aluminium dross processing

A process for recovering aluminium metal from aluminium dross by processing of said aluminium dross, said process comprising:

• transporting hot dross from a furnace containing molten aluminium producing said dross, said hot dross comprising oxides and an initial content of metallic aluminium and being contained in and part filling a dross processing receptacle;
• said dross processing receptacle comprising two opposed end walls, two opposed side walls, a floor and a removable lid wherein said opposed end walls each comprise at least one outlet for pouring molten aluminium from the receptacle, said at least one outlet in each of said opposed end walls being positioned at a height part way between a floor of said receptacle and said lid closing said receptacle, and wherein said receptacle further comprises external cooling fins attached to an outer surface of the receptacle;
• placing said dross processing receptacle onto a rocking device mounted on a support structure, wherein said rocking device comprises a mounting and a rocking mechanism for rocking said mounting, for rocking said receptacle to lower alternately said opposed ends of the receptacle;
• operating the rocking device to lower alternately said opposed ends of the receptacle to pour molten aluminium out of said at least one outlet into a container for catching molten aluminium which pours from said at least one outlet;
• and
• continuing said rocking and pouring until at least 70 wt % of the initial content of metallic aluminium has been poured.
