The exploitation of bauxite a fundamental field of mineral wealth of Greece. Exploitable deposits of bauxites are areas of mountain Parnassos, Giona and Helicon (central Greece) is estimated at 100 million tonnes. Economically significant bauxite occurrences are mountains Kallidromon, Iti and Othrios, Evia, Skopelos, Eleusis, etc.

In addition to expanding and upgrading the alumina refinery, the company also indicated that it will be moving its corporate headquarters to the Gramercy plant.

The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.

In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite. The aluminum is precipitated out of solution in the form of aluminum hydroxide, Al(OH) 3. The aluminum hydroxide is then calcined to form alumina, Al 2 O 3. Aluminum is smelted from the alumina using the HallHeroult Process.

Extraction of Aluminium from Bauxite. In the first stage is called as the pure alumina (Al2O3) is obtained from bauxite and in the second state is called as the electrolysid of (Al2O3) in molten cryolite (Na3AlF6) is carried out. Bauxite contains SiO2, iron oxides and Ti (IV) oxide as impurities.
