Extraction of Aluminium
The aluminium settles at the bottom of the cells, while the oxygen combines with carbon to make carbon dioxide. Special vacuum buckets are used to extract the aluminium from the cells, after which it is taken to the cast house once the bucket is full. At the cast house, the aluminium is cast into ingots, weighing between 6kgs and 30 tonnes.
