from the non-saline dross produced in the manufacture of metallic aluminum in holding
furnaces. Three types of input drosses were used with Al2O3 contents ranging from 58 to 82
wt%. Calcium aluminates were formed via the mechanical activation (reactive milling) of
different mixtures of dross and calcium carbonate, sintering at 1300° C. The variables
affecting the process, especially the milling time and the Al2O3/CaO molar ratio, were …
