Technoeconomic Assessment of the Carbothermic Reduction

Abstract. In pursuit of the aluminum industry Vision and Roadmap goals, the Department of Energy has partially supported a consortium of Alcoa and Elkem in the development of the Aluminum Carbothermic Technology — Advanced Reduction Process (ACT-ARP), which promises significant energy and emission reductions.

Carbothermic reactionWikipedia

A key step in this process is the reduction of sodium sulfate with coal Na 2 SO 4 2 C → Na 2 S 2 CO 2. The Na 2 S is then treated with calcium carbonate to give sodium carbonate, a commodity chemical. Recently, development of the 'MagSonic TM ' carbothermic magnesium process has restarted interest in its chemistry MgO C ↔ Mg CO
