Abstract
Un procedimiento para la recuperación de metales no férricos de calcinados conteniendo óxido de hierro del tipo que contienen el metal no férrico encapsulado en y/o en solución sólida en el óxido de hierro, caracterizado porque comprende las etapas de realización siguiente: (i) hacer reaccionar el calcinado con un ácido inorgánico fuerte en fase líquida mientras se agita la masa reaccional durante tiempo suficiente para que sustancialmente todo el hierro presente forme una sal de hierro acuosoluble, (ii) adicionar agua a la masa reaccional, (iii) separar la fase líquida de la fase sólida, y (iv) recuperar los metales no férricos de una o ambas fases.
