Secondary alumina is the byproduct of dry scrubbing in aluminum smelting. Secondary alumina has superior dissolution characteristics to primary alumina. Secondary alumina dissolves in pieces in molten cryolite, which results in larger contact area and better diffusion kinetics.


Small crucible furnaces are used to produce Aluminium Alloys for casting. Larger melting operations use reverberatory furnaces. The final step in the production process is chlorination to obtain a high quality Aluminium product. 3.2 Definitions Secondary Aluminium production: - production of Aluminium from materials other than ores.
