The goal of this work was to study the salt/oxide interactions during the process of aluminum
recycling in rotary furnaces, which uses salts to protect the burden. Microstructure analysis
was the main tool to analyze the morphologies of aluminum dross and its interactions with
liquid salt flux; consequently the study was carried out through scanning electron
microscope coupled with an energy dispersive X-ray spectrometry detector. Drosses
collected from aluminum can recycling industries were used. Tests were carried out using …
