Abstract: During the primary and secondary aluminium processing, aluminium dross is formed on the surface of molten aluminium that is exposed to furnace atmosphere. Dross generation in aluminium casthouse is tagged as an unavoidable evil. Microstructure analysis is the main tool to analyze the morphologies of aluminum dross. The dross samples characterized in this study are collected from Emirates Aluminium (EMAL). The dross came from a furnace that operates at 950oC set temperature with 1050oC roof temperature and an oxygen transmitter of 13.6{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}. To be able to effectively maximize the metal recovery from dross, explore its sustainable use as a by-product and understand its impact on environment when used as landfills, they need to be characterized to study their properties. The results revealed the quantity of aluminium and other components in the dross. The specific heat experiment carried out on the dross sample gives a clue about the thermal heat storage capacity of this material.
