Claims (1)

  1. 미리파쇄(破碎), 자선(磁選)된, 스라그로부터 선별된 자착물(磁着物)을 마쇄기(摩碎機)에 의해 마쇄하고, 지금(地金)과 그밖의 부분으로 분급 선별하여, 동(同) 분급 선별된(地金)을 0.5∼3m/m의 사분(篩分)하고, 이 사하산물(篩下産物)을 미분쇄기(微粉碎機)에서 마쇄하여, 이 마쇄산물은 사분과 분급을 소요회수 되풀이 한후, 자선별(磁選別)에 의하여 비장성물을 분리제거하여 금속철분을 만들고, 한편으로상기 0.5∼3m/m의 사분시에 있어서, 사상물(篩上物)은 다시 마쇄기에 송급하여 마쇄를 되풀이 하는것을 특징으로 하는 제철소로부터 발생하는 스라그로부터 철분을 제조하는 방법.
