The kinetics of aluminium deposition from NaCI-AICl, melts (c,,,,, < 10 mol%) contained in alumina crucibles was studied by linear sweep voltammetry and potential step amperometry at temperatures around 820Β°C. At low concentrations (r,,,, I c 0.4 mol %) the reduction of AlCl, on iiquid aluminium has
Among the various steps of aluminium production from liquid metal, a lot of scrap is generated due to machining operations. Therefore, recycling of aluminium scrap is an interesting subject because of the broad applications of this metal and low efficiency of processes used to recycle metal scrap. I
