ALUMINIUM (ORIGION TO APPLICATIONS)

 Non-ferrous metal material is widely used in almost everyday life.

ORIGIN OF ALUMINUM:

A rock named a bauxite ore forms from laterite soil which has likely an appearance of reddish clay. a rock founds in the tropical or subtropical regions (An earth that lies roughly middle of the Globe).

Bauxite is not full of Aluminum. It has a relatively higher content of Aluminum. Apart from Aluminum, bauxite is comprised and available of:

Silica -inorganic ceramic materials composed of silicon dioxide -SiO2-,

IRON Oxide -chemical compounds composed of iron and oxygen-,

TITANIUM DIOXIDE TiO2 -A naturally occurring oxide sourced from ilmenite, rutile and anatase these are the main minerals of TiO2-, Even Aluminum oxide Compounds -Alumina-.

Several other most important ores do exist in relative percentage of Aluminum.

 (i) Silicate:

      i.        Kaolin (Al2 O3.2SiO2.2H2O)            

     ii.        Potash felspar (K2O.Al2O3.6SiO2) 

     iii.        Potashmica (K2O.Al2O3.6SiO2.2H2O).

(ii) Fluoride:

      i.        Cryolite (Na Al F6)

(iii). Sulphate:

      i.        Alunite [K2SO4.Al (SO4)3.4Al(OH)3]

(iv). Oxides:

      i.        Bauxite (Al2O3.2H2O)

     ii.        Gibbisile (Al2O3.3H2O)

     iii.        Diaspore (Al2O3.H2O)

    iv.        Corundum (Al2O3)

Aluminium is a Third in Abundance in nature
