Again, IANAM...but an aluminum smelter produces bulk metallic aluminum from ores (generally aluminum oxide, Al2O3). Vs. the input to a steel mini-mill is almost all bulk & scrap steel (not ire ore), and its output is various steel products - bars, beams, pipes, rebar, wire, sheets, and such. https://en.wikipedia.org/wiki/Aluminium_smelting https://en.wikipedia.org/wiki/Aluminium_smelting https://en.wikipedia.org/wiki/Steel_mill https://en.wikipedia.org/wiki/Steel_mill
