A continuous process for the production of elemental aluminum is described. Aluminum is made from aluminum oxide and a reducing gas such as a light hydrocarbon gas or other reducing gas, for example hydrogen. In the process, a feed stream of the aluminum oxide and the reducing gas is continuously fed into a reaction zone. There the aluminum oxide and reducing gas are reacted at a temperature of about 1500&deg; C. or greater in the reaction zone to provide a continuous product stream of reaction products, which include elemental aluminum. The product stream is continuously quenching after leaving the reaction zone, and the elemental aluminum is separated from the other reaction products.
