Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA REDUCIR UNA MENA DE METAL PARTICULADA. EL PROCEDIMIENTO CONSISTE EN CALENTAR UNA PRIMERA CORRIENTE DE GAS INERTE, ALIMENTAR ESA CORRIENTE HACIA UNA ZONA DE REDUCCION SECUNDARIA, Y A CONTINUACION SE SEPARA UNA SEGUNDA CORRIENTE DE GAS QUE CONSISTE EN UN GAS INERTE Y UN GAS REDUCTOR, SE ENFRIA LA SEGUNDA CORRIENTE Y SE HACE CIRCULAR LA MISMA HACIA LA ZONA DE REDUCCION SECUNDARIA COMO LA PRIMERA CORRIENTE. LA PRIMERA CORRIENTE SE CALIENTA A 600G-900GC; EL GAS EMPLEADO ES NITROGENO. EL APARATO CONSTA DE LOS SIGUIENTES ELEMENTOS: 1. UN REACTOR DE EJE VERTICAL QUE TIENE UNA ZONA DE REDUCCION PRIMARIA. 2. UNA ZONA DE ENFRIAMIENTO EN LA PORCION INFERIOR DEL REACTOR Y UNA ZONA DE REDUCCION SECUNDARIA. 3. UN DISPOSITIVO PARA SUMINISTAR GRAS REDUCIDO, CALENTADO HACIA EL REACTOR CERCA DEL FONDO DE LA ZONA DE REDUCCION PRIMARIA. 4. UN DISPOSITIVO PARA SUMINISTRAR GAS REFRIGERANTE. 5. UN MEDIO DE CALENTAMIENTO EN EL CIRCUITO PARA CALENTAR EL GAS QUE ENTRA EN EL REACTOR. 6. UN DISPOSITIVO DE BOMBEO. A
