An aluminium smelter consists of a large number of cell (pots) in which the electrolysis takes place. A typical smelter contains anywhere from 300 to 720 pots, each of which produces about a ton of aluminium a day, though the largest proposed smelters are up to five times that capacity. Smelting is run as a batch process, with the aluminium metal deposited at the bottom of the pots and periodically siphoned off.

In 1963, the Romanian Government decided to build the country's first and only aluminum smelter, Alro, in Slatina. The first batch of Romanian aluminum was produced in 1965. From 1982 to 1989 the smelter's production capacity was gradually brought up to 263,500 tonnes annually.

Overview of the Point Henry smelter, operated by Alcoa World Alumina and Chemicals in Australia. Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.
