Abstract

The present invention relates to a method of manufacturing a binderless briquette and an apparatus for performing the same. The method of manufacturing the binderless briquette includes providing a dust gathered by using a dry collection manner from an offgas discharged when an iron ore is dried, providing a reduced iron ore discharged from an apparatus for manufacturing a molten iron including a reduction furnace providing a reduced iron obtained by reducing the dried iron ore and a melter-gasifier manufacturing the molten iron by melting the reduced iron, providing a sludge discharged from the apparatus for manufacturing the molten iron, providing a mixture formed by drying and mixing at least two sources selected from the group consisting of the dust, the reduced iron ore and the sludge and forming the binderless briquette by molding the mixture without adding a binder.
