Aluminium production process

REDUCTION PROCESS At an aluminium smelter, alumina is poured into special reduction cells with molten cryolite at 950⁰С. Electric currents are then induced in the mixture at 400 kA or above; this current breaks the bond between the aluminium and oxygen atoms resulting in liquid aluminium settling at the bottom of the reduction cell.

New process efficiencies in aluminium smelters

the electrolytic cells in aluminium smelters are based on either co-current (parallel) or cross-current processes. In the co-current process the ad-sorbent (alumina) is introduced upstream of a reactor, where it mixes with the gas. Adsorption is achieved through thorough contact between the alumina particles and the gaseous fluoride (hydrogen flu-
