To produce one tonne of aluminium, about two tonnes of alumina are required. The smelting process is done in large steel, carbonlined furnaces called reduction cells. When alumina is fed into these cells, it gets dissolved in molten cryolite, a liquid which can dissolve alumina and conduct electricity at 970°C.
