Recovery of valuable products from hazardous aluminum ...

Aluminum dross is a toxic industrial waste generated in large quantities in aluminum smelter plants. The presence of leachable salts like NaCl and KCl in aluminum dross aggravates the environmental crisis, whereas the metallic aluminum entrapped in the matrix of alumina can be used as raw material for metal extraction.


aluminum industry produces approximately 3.2 million tons of dross annually from domestic aluminum smelting. Most of the interest has been on the recovery of the aluminum content of the dross, as white dross can reach as high as 80wt%. In order to recover the metallic aluminum, dross is heating in a rotating furnace with a salt flux introduced.
