Aluminum Sulphate ( Alum )

Aluminium sulphate, commonly known as alum is a hard crystalline solid or powder that is soluble in water. It contains around 17% alumina (Al2O3). It is manufactured in a simple process from aluminium trihydrate and sulphuric acid. Aluminium sulfate has been used by man since 2000 BC, when the Egyptians used a mineral alum as a mordant in dyeing.

Extracting aluminum from dross tailings

Abstract. Aluminum dross tailings, an industrial waste, from the Egyptian Aluminium Company (Egyptalum) was used to produce two types of alums: aluminum-sulfate alum [itAl 2 (SO 4)3.12H 2 O]and ammonium-aluminum alum [(NH 4)2SO 4 AL 2 (SO 4)3.24H 2 O]. This was carried out in two processes.
