Abstract: Molten aluminum is treated with selectively maintained salt flux in a compact efficient system to decrease its oxide, gas and sodium content. Gas removal is further aided by stripping with a non-reactive stripping gas. The system features an intensely agitated zone for contacting the metal and the salt flux followed by a quiet separation zone. Molten metal introduction, agitation and flux characteristics are utilized to achieve the required efficiencies.

Abstract: Aluminum is purified by chloridizing a molten body of aluminum in a highly efficient manner. High metal chloridization rates are achieved in a system wherein chlorine utilization efficiency is 100 percent or very closely approaches this level. The system includes a chlorine-metal contacting technique which includes an agitator and which controls and maintains contacting conditions to optimize efficiency.
