On trending technologies of aluminium dross recycling: A review
In this work, a novel carbon-free smelting reduction process is proposed to recover valuable metals from molten copper slag, in which secondary aluminum dross is used as the reductant via co-modification with CaO and Na 2 O additions. The influence of Na 2 O addition on the metal recovery and slag properties under different CaO/SiO 2 …
