Zusammenfassung:	An apparatus and a method for drying fine ores are provided to dry fine ores efficiently and increase energy efficiency. An apparatus(100) for drying fine ores comprises at least one reduction furnace(201) for reducing fine ores, and a fine ore drying unit(10) for receiving flue gas exhausted from the reduction furnace to dry the fine ores, and charging the dried fine ores into the reduction furnace. The apparatus further comprises a dust remover(90) for removing dust contained in the flue gas to dry the fine ores by the drying gas after separating drying gas from flue gas exhausted from the dust remover. The fine ore drying unit includes a fine ore dryer(80) for receiving the fine ores and the flue gas to dry the fine ores, fine ore storage bins(82), and a fine ore charging machine(84). The fine ore storage bins have a fine ore supply bin(821) and a horizontal conveyor belt(823) installed thereabove and a vertical conveyor belt(841) installed therebelow. The fine ore charging machine includes two fine ore charging tanks(843,845) and a valve(844).
