Abstract

PROCEDIMIENTO PARA LA PREPARACION DE CONCENTRADOS DE DIOXIDO DE TITANIO.CONSISTE EN SEPARAR EL HIERRO, MANGANESO, VANADIO EN FORMA DE CLORUROS, DEL MATERIAL DE PARTIDA QUE PUEDE SER: ILMENITA, LEUCOXENA O TITANOMAGNETITA. EL PROCEDIMIENTO INCLUYE: LAVAR CON AGUA EL MATERIAL CLORADO QUE CONTIENE OXIDO DE TITANIO; TRANSFORMAR A VALENCIA 0 AL MENOS EL 1 DEL FE CONTENIDO, USANDO COMO REDUCTORES, SOLIDOS O GASEOSOS, CARBONO (EN FORMA DE COQ), HIDROGENO, GAS NATURAL, CO O COMBINACIONES DE ELLOS; CONTACTAR GASES CLORADOS CON EL MATERIAL RESULTANTE DE LAS DOS FASES ANTERIORES, HACIENDO CIRCULAR EL GAS ENTRE 2 Y 100 CM/SEG. EN LA SEGUNDA FASE EL REDUCTOR GASEOSO, DE EMPLEARSE, CIRCULA ENTRE 1 Y 100 CM/SEG Y LA TEMPERATURA ESTARA COMPRENDIDA ENTRE 500 Y 1.300 JC. LA TEMPERATURA DE LA FASE DE CLORACION ESTARA COMPRENDIDA ENTRE 300 Y 1.300JC.
