Zusammenfassung:	Disclosed is a dry type fine iron powder pick-up method from steel slag powder, which comprises utilizing wind power of draught fans in ball grinder's dust collector to blow the non-magnetic substance to the product exhaust port from the high-strength fine magnet separator, thus making the content of the extracted micro steel particles (powder) reach above 55%, then employing belt-type two-way magnet separator for refining, so that the content of the extracted refined iron powder can reach above 80%, and the iron content of the obtained steel slag tailing powder is below 1%.
