Abstract
Un procedimiento para la obtención de aluminio metálico, en el cual una corriente en circulación de escoria de alúmina fundida, que contiene carburo de aluminio, se hace pasar a través de una o más zonas de temperatura relativamente baja, donde se introduce alimentación de carbono para que reaccione con la alúmina y forme carburo de alumino adicional con desprendimiento de gas monóxido de carbono, y a través de una o más zonas de alta temperatura, mantenidas a una temperatura más alta, de tal modo que el carburo de aluminio reaccione con la alúmina para producir metal aluminio, con desprendimiento de gas monóxido de carbono, que tiene un contenido importante de subóxido de aluminio gaseoso y de vapor de aluminio, caracterizado porque el gas monóxido de carbono desprendido en dicha zona o zonas de alta temperatura, se pone en contacto con escoria de alúmina fundida, que contiene carburo de aluminio disuelto, a una temperatura menor que la de dicho gas, efectuándose dicho contacto en condiciones para llevar a efecto un enfriamiento substancial de dicho gas y, de este modo, llevar a efecto una reacción por lo menos parcialmente exotérmica de su contenido de vapor de subóxido de aluminio y de aluminio, con monóxido de carbono.
