The production journey from bauxite to aluminium coil

The Journey of Aluminium

Aluminium's story begins with bauxite ore extracted from the earth and, through advanced production processes, becomes high-quality aluminium products.

“Thanks to its light weight and recyclability, aluminium is one of the essential materials of modern industry.”

Bauxite Mining

The first step in aluminium production is the extraction of bauxite ore. Bauxite is a natural resource rich in aluminium oxide.

Alumina Production

The extracted bauxite is processed by the Bayer process to obtain aluminium oxide (alumina). Precipitation, purification and calcination stages produce high-purity alumina.

Smelting Process

The alumina is dissolved in cryolite in electrolysis cells and reduced by an electric current. In this process the aluminium separates from the oxide to give molten aluminium.

Primary Aluminium

The molten aluminium is collected in casting ladles and cast into the required form. Purity and homogeneity are checked against high quality standards.
