Abstract

PROCEDIMIENTO PARA PREPARAR NODULOS A PARTIR DE MATERIAS PRIMAS DE MENA DE HIERRO CONTENIENDO ARSENICO COMO IMPUREZA. SE MEZCLA UNA MENA DE HIERRO QUE CONTIENE ARSENICO, TAL COMO ESCORIA DE PIRITA, CON UN MATERIAL DEL TIPO DE BREA QUE ACTUA COMO AGENTE REDUCTOR Y DE COMBINACION, TAL COMO BREA DE CRACKING TERMICO RETARDADO, BREA DE ALQUITRAN MINERAL DE CRACKING TERMICO, EXTRACTO DE PETROLEO Y CARBON REFINADO SOLVENTE, GRANULANDO LA MEZCLA PARA FORMAR NODULOS, Y CALCINANDO LA MEZCLA GRANULADA EN UNA ATMOSFERA REDUCTORA. SE UTILIZAN COMO MATERIAL INICIAL EN LA FABRICACION DEL HIERRO Y DEL ACERO.
