Aluminium is obtained from alumina, a compound of aluminium and oxygen which is processed from bauxite (a mineral found in all tropical and sub-tropical countries).

Aluminium is produced by electrolytically separating oxygen from alumina ore. This is done in a reduction cell. The reduction cell is a large steel shell lined with carbon, Cryolite, aluminium fluoride and alumina (bath materials) which are placed in the cavity of the shell. This acts as the cathode in the electrolytic process. Above the cathode, 18 carbon anodes are attached by copper rods to the cell’s superstructure. The anodes are lowered into the cathode bath material.

An electrical current is passed from the anode to the cathode breaking the bond between the aluminium and the oxygen. Oxygen combines with the carbon anode to form carbon dioxide which is driven off as a gas. Molten aluminium collects at the bottom of the cell to be siphoned out as the final step in the process.

VALCO imports various materials used in the aluminium making process. Our Carbon plant manufactures the necessary carbon anodes. Electricity and fuel are purchased in Ghana. All these come together in a facility that is technologically contemporary managed and staffed with dedicated professionals all of whom are Ghanaians.
