The article presents the results of technological research, which is the basis for the development of a scheme for the staged magnetic concentration of low-titanium magnetite ore from the Suroyamskoe deposit. The object of the research was technological samples of primary titanomagnetite ore with a mass fraction of total iron of 13.87% and titanomagnetite ore from the upper oxidized zone of the deposit, with a mass fraction of total iron of 10.97%. During laboratory tests, the material constitution, physical and mechanical properties, crushability, grindability and processibility of the samples by magnetic separation were determined. It is found that the material constitution of the ore sample from the oxidized zone features the increased mass fraction of aluminum oxide and silicon oxide, as well as the presence of sphene, which indicates the formation of clay minerals in the processes of natural weathering and dissociation of rocks. For primary titanomagnetite ore, the possibility of coarse dry magnetic separation of the initial ore with a particle size of –20 + 5 mm is found, which allows extraction of the magnetic fraction at the yield of 55.26% and the mass fraction of 20.8% Fe total at the recovery of 83.41%. For weathered oxidized titanomagnetite ore, washing is found to be expedient, which allows increasing the mass fraction of iron before wet magnetic separation by 2.1% at the iron extraction of 86.8% in washed ore and reduced mass fraction of titanium by 0.3%. According to the proposed technology of the staged magnetic separation, it is possible to extract a good-quality iron concentrate with iron mass fraction of 63.1% from the ledge ore of the of the Suroyamskoye deposit. The concentrate with a rather high mass fraction of iron of 58.2% can be obtained from the low-grade weathered oxidized ore. Simple circuits, structural arrangements and low costs of the proposed technologies for processing low-titanium ore from the Suroyamskoye deposit will allow production of iron concentrates suitable for use at metallurgical plants of the Chelyabinsk Region.
