Metallurgy, art and science of extracting metals from their ores and modifying the metals for use. 1. While the cells (or 'pots') vary in size from one plant to another, the fundamental process is identical and is the only method by which aluminium is produced industrially. The electrical current passes from the carbon anodes via the bath, containing alumina in solution, to the carbon cathode cell lining. In addition to carbon dioxide, the aluminium smelting process also emits hydrogen fluoride (“HF”) - an extremely toxic gaseous emission. among the people to reach a common understanding. These electrolytic cells are the nerve centre of the process. Log in. The aluminium is siphoned from the bottom of the cell in a process called tapping (done by rotation every 32 hours), and transported to dedicated casting operations where it is alloyed; then cast into ingots, billets and other products.
