Abstract
content ranges from 50.69 to 51.88%; bivalent iron is present in small quantities-the FeO content in the samples ranges from 3.53 to 4.16%. The content of magnetic iron is 11.40-12.67%. Based on the obtained results by the investigation of the features of magnetite-hematite ores from the Mikhailovskoye deposit, a technological scheme of magneto-flotation beneficiation was proposed, which allows producing iron concentrates with 69% of iron content and less than 2.7% silicon dioxide for the production of pellets with subsequent metallization.
