Abstract

PROCESO PARA VALORAR EL MATERIAL DE TITANIO PARTICULADO QUE CONTIENE OXIDOS DE HIERRO QUE CONSISTE EN A): PONER EN CONTACTO EN UN HORNO DE REDUCCION MECANICA, MATERIAL PORTADOR DE TITANIO PARTICULADO, MATERIAL CARBONACEO PARTICULADO COMO AGENTE REDUCTOR, Y HCL O UNO O MAS MATERIALES QUE PRODUZCAN HCL DURANTE LA FASE A), O MEZLAS DE ESTOS, DICHA PUESTA EN CONTACTO SE REALIZA EN AUSENCIA SUSTANCIAL DE CLORACION DE TITANIO Y MIENTRAS (I) EL HORNO DE REDUCCION MECANICA GIRA Y SE DEJA CAER EN FORMA DE CASCADA LOS MATERIALES EN SU INTERIOR, (II) SE MANTIENE UNA TEMPERATURA DE APROXIMADAMENTE 900-1.100 GRADOS C, Y (III) SE MANTIENEN LAS CONDICIONES DE REDUCCION, TENIENDO DICHO MATERIAL DE TITANIO PARTICULADO UN DIAMETRO MEDIO INFERIOR A APROXIMADAMENTE 40 MICRONES, DICHO DIAMETRO EXISTE EN EL MINERAL QUE ES INTRODUCIDO DENTRO DEL HORNO O SE TRITURA EN EL HORNO PARA TENER TAL DIAMETRO, CONVIERTIENDO EN DICHA ETAPA (A) OXIDO DE HIERRO EN HIERRO METALICO Y LIBERANDO HIERRO METALICO DEL MATERIAL DE TITANIO, CONTINUANDO ESTA PUESTA EN CONTACTO HASTA QUE EL HIERRO PRODUCIDO EN LA ETAPA (B) TENGA UN DIAMETRO MEDIO DE AL MENOS APROXIMADAMENTE 50 MICRONES, B) ELIMINANDO LOS PRODUCTOS RESULTANTES DE LA ETAPA (A), DEL HORNO, Y (C) SEPARANDO EL HIERRO METALICO Y EL MATERIAL DE TITANIO DE LOS PRODUCTOS RESULTANTES DE LA ETAPA (B).
