Properties and Raw Materials
Aluminum is the third-most plentiful element in the earth’s crust, and it makes up 8% of the planet’s soil and rocks. In nature, aluminum is found only in chemical compounds with other elements, such as sulfur, silicon, and oxygen. The only place where aluminum can be extracted profitably is in the form of aluminum ores.
Bayer Process
Initially, the bauxite ores are obtained and then crushed mechanically. The crushed ore is then mixed with caustic soda and put into a grinding mill, then made into a slurry containing the ore. The slurry is then pumped into the digester. The digester is a large tank that acts like a pressure cooker.

Overview
An alum is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula XAl(SO 4) 2·12 H 2O, where X is a monovalent cation such as potassium or ammonium. By itself, "alum" often refers to potassium alum, with the formula KAl(SO 4) 2·12 H 2O. Other alums are named after the monovalent ion, such as sodium alum and ammonium alum.
History
The western desert of Egypt was a major source of alum substitutes in antiquity. These evaporites were mainly FeAl 2(SO 4) 4·22 H 2O, MgAl 2(SO 4) 4·22 H 2O, NaAl(SO 4) 2·6 H 2O, MgSO 4·7H 2O and Al 2(SO 4) 3·17 H 2O. The Ancient Greek Herodotus mentions Egyptian alum as a valuable commodity in The Histories.
The production of potassium alum from alunite is archaeologically attested on the island Lesbos. …
Production
Some alums occur as minerals, the most important being alunite.
The most important alums – potassium, sodium, and ammonium – are produced industrially. Typical recipes involve combining aluminium sulfate and the sulfate monovalent cation. The aluminium sulfate is usually obtained by treating minerals like alum schist, bauxite and cryolite with sulfuric acid.

Chemical properties
Aluminium-based alums have a number of common chemical properties. They are soluble in water, have a sweetish taste, react as acid by turning blue litmus to red, and crystallize in regular octahedra. In alums each metal ion is surrounded by six water molecules. When heated, they liquefy, and if the heating is continued, the water of crystallization is driven off, the salt froths and swells, and at last an amorphous powder remains. They are astringent and acidic.
Uses
Aluminium-based alums have been used since antiquity, and are still important in many industrial processes. The most widely used alum is potassium alum. It has been used since antiquity as a flocculant to clarify turbid liquids, as a mordant in dyeing, and in tanning. It is still widely used in water treatment, in medicine, for cosmetics (in deodorant), in food preparation (in baking powder and pickling), and to fire-proof paper and cloth.
