Abstract
RECUPERACION DEL ALUMINIO LIBRE CONTENIDO EN ESCORIAS DE ALUMINIO UTILIZANDO ENERGIA DE PLASMA SIN FUNDENTE SALINO. SE DESCRIBE UN PROCEDIMIENTO PARA RECUPERAR ALUMINIO LIBRE Y COMPUESTOS DE ALUMINIO, TALES COMO OXIDO DE ALUMINIO, DE ESCORIAS DE ALUMINIO EN UN HORNO CALENTADO CON UNA ANTORCHA DE ARCO DE PLASMA, ALIMENTADA PREFERIBLEMENTE CON AIRE COMO GAS DE ARCO. EL USO DE ENERGIA DE PLASMA PARA CALENTAR EL HORNO ELIMINA LA NECESIDAD DE UN FUNDENTE SALINO, LOGRANDO UN PROCEDIMIENTO QUE ES ECOLOGICAMENTE SEGURO Y DE COSTE ECONOMICO. TAMBIEN SE DESCRIBE UN PROCEDIMIENTO PARA CONVERTIR COMPUESTOS DE ALUMINIO NO METALICOS EN OXIDOS DE ALUMINIO SUSTANCIALMENTE PUROS CALENTANDO LOS COMPUESTOS CON UNA ANTORCHA DE PLASMA ALIMENTADA CON UN GAS OXIDANTE COMO GAS DE ARCO.
