In the remelting process, pure aluminum is initially heated at around 800°C, followed by the addition of metal scrap. It is sometimes challenging to maintain the operating temperature as cold scrap metal is fed in periodically. The dross on top of the metal bath is skimmed continuously. In Eggen et al.,23the remelting process …
