Zusammenfassung:	The present invention relates to a method for recycling FeNi lump slag, and specifically, to a method for recycling FeNi lump slag, including the steps of: pulverizing the FeNi lump slag to a particle size of 25 mm or less to obtain FeNi lump slag particles; separating the particles having a particle diameter of 5 to 25 mm among the FeNi lump slag particles into high strength particles and particles having a particle diameter of less than 5 mm into low strength particles; and pulverizing the low strength particles to fineness of 3,000 to 4,650 cm^2/g. 본 발명은 FeNi 괴재슬래그를 재활용하는 방법에 관한 것으로, 상세하게는 FeNi 괴재슬래그를 입경 25mm 이하로 분쇄하여 FeNi 괴재슬래그 입자를 획득하는 단계; 상기 FeNi 괴재슬래그 입자 중 입경 5~25mm의 입자를 견경부 입자, 입경 5mm 미만의 입자를 취약부 입자로 분리하는 단계; 및 상기 취약부 입자를 3,000 내지 4,650cm2/g의 분말도로 분말화하는 단계를 포함하는, FeNi 괴재슬래그 재활용 방법을 제공한다.
