This paper studies the possibility of obtaining additional concentrate from the processing tailings of titanomagnetite ore of the Gusevogorskoye deposit. The potential value of the tailings decreases between the first and the last processing stages. The mass fraction of iron in the concentrates obtained from these tailings drops between dry magnetic separation tailings and wet magnetic separation tailings of the last stage (from 52.12 to 19.23 %). These values are significantly lower than the mass fraction of iron in the concentrate (62.05 %) obtained in the processing of an ore sample. Additional processing of the fine fraction of dry magnetic separation tailings rendered a product with a mass fraction of iron comparable to that in the original ore. Therefore, additional processing of dry magnetic separation tailings is a promising method for increasing the concentrate yield. Processing of the current dry magnetic separation tailings would generate additional 277,000 tons of raw materials per year with zero production and crushing costs. Higher magnetic field induction in wet magnetic separation of the first stage, with the existing technology, would increase the concentrate yield, but reduce the mass fraction of iron in it. Additional processing of the combined tailings of the wet magnetic separation of the second, third, and fourth stages is not advisable.
