The smelter consists of two high-amperage potlines that use Pechiney technology. Together they produce 740,000 metric tons of aluminum per year. Besides of potlines, the Ras Al Khair Aluminium Smelter also contains a carbon plant for anode production and baking, the world’s largest integrated cast house (with 15 furnaces), maintenance, administration, and support facilities, and a rail line transports bauxite feedstock from a mine at Al Ba’itha. The bauxite is refined at Ras Al Khair to yield alumina for smelting.
The two potlines of Aluminium Smelter include 720 smelting furnaces, or pots, comprising 4 pot rooms of 180 pots each. Each pot room is three-quarters of a mile (1.2 kilometers) long. The construction required 298,000 cubic yards (228,800 cubic meters) of concrete and 48,000 metric tons of structural steel.
