The invention discloses an ore dressing method for improving ore dressing recovery rate of low-grade refractory specularite. The ore dressing method adopts the following processes and steps: the low-grade refractory specularite with iron grade not greater than 28.0% is crushed and grinded to 82-88% of -0.076 mm; one-stage magnetic separation iron ore concentrates are obtained beforehand by one-stage strong magnetic roughing; the continuous magnetic separation operation of one-stage strong magnetic scavenging I and one-stage strong magnetic scavenging II is performed for strong magnetic roughing tailings to cast out one-stage strong magnetic separation tailings; concentrates of one-stage strong magnetic scavenging I and one-stage strong magnetic scavenging II are merged, and are grinded to 86-94% of -0.043 mm; and after the continuous magnetic separation operation of two-stage strong magnetic roughing I, two-stage strong magnetic scavenging I and two-stage strong magnetic scavenging II is performed to cast out two-stage strong magnetic separation tailings, two-stage magnetic separation iron ore concentrates are obtained. The method not only can obtain part of qualified iron ore concentrates beforehand, but also can cast out the tailings with iron grade less than 10% beforehand; the ore quality in two-stage ball milling (middling) can be largely decreased; and the milling separation energy consumption can be largely reduced.
