Aluminium Smelting Process Flow Chart - KMC Aluminium

2021-9-21  Aluminium Smelting Process Flow Chart. Aluminium in the form of bauxite ore is the third most abundant element found on earth after oxygen and silicon. Alumina or aluminium oxide is extracted from bauxite ore by means of the Bayer process. Aluminium smelting is the process by which an aluminium company extracts aluminium from its oxide, Alumina.

Chapter 2. Production and Processing of Aluminum

1999-5-7  The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.

Aluminium production process

REDUCTION PROCESS At an aluminium smelter, alumina is poured into special reduction cells with molten cryolite at 950⁰С. Electric currents are then induced in the mixture at 400 kA or above; this current breaks the bond between the aluminium and oxygen atoms resulting in liquid aluminium
