In the previous report, two main processes relating to the direct reduction of aluminum were described in detail, namely the one is the carbothermic production of crude aluminum alloys and the other is the decomposition method using carbide, nitride, etc., and especially we discussed on the former process.
In this report, the experimental results of equilibrium, Kinetics and refining of the subchloride process are described. Furthermore, various other industrial examination for the refining of aluminum from crude alloys are also discussed on the basis of published papers and patents.
