Beschreibung
Zusammenfassung:	The invention relates to the technical field of iron ore beneficiation, in particular to a beneficiation method for resource utilization of magnetite concentrate. A common magnetite concentrate raw material is divided into a first-stage magnetite concentrate raw material and a second-stage magnetite concentrate raw material; the separation process of the first-stage magnetite concentrate raw material comprises the steps of hydrocyclone classification, tower milling by a tower mill, magnetic roughing, first-stage magnetic concentration and second-stage magnetic concentration; the separation process of the second-stage magnetite concentrate raw material comprises the steps of hydrocyclone classification, tower milling of a tower mill, first-stage magnetic separation concentration and second-stage magnetic separation concentration; the separation process is simple, flotation or chemical beneficiation is not used in the process, demagnetization treatment is not needed before first-stage magnetic separation concen
