Aluminium dross is a by-product formed during the melting and processing of aluminium. When aluminium is in its molten state, it undergoes oxidation on the surface, resulting in the formation of a 'skin like' layer known as dross. In the past, aluminium dross was disposed in landfills, a practice deemed hazardous to the environment.

Aluminum dross tailings, an industrial waste, from the Egyptian Aluminium Company (Egyptalum) was used to produce two types of alums: aluminum-sulfate alum [itAl2(SO4)3.12H2O]and ammonium-aluminum alum [(NH4)2SO4AL2(SO4)3.24H2O]. This was carried out in two processes. The first process is leaching the impurities using …
It is then crushed to produce relatively uniformly sized material. The ore is then fed into large grinding mills and mixed with a caustic soda solution (sodium hydroxide) at high temperature and pressure. The grinding mill rotates like a huge drum while steel rods - rolling around loose inside the mill - grind the ore to an even finer consistency.
