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.
