A new method is proposed for agglomerating iron-ore-bearing materials. The method involves moistening the charge with up to 7.5–9% pulp containing dust-sized waste products from the processing of brown iron ores. The ores are ferruginous chlorites (chiefly amesite, chamosite, and penninite). The have a coarseness of 0.074 mm. The ore content of the pulp is within the range 1.5 to 75 wt. %. The chlorites have the following chemical composition (wt. %): Fe2O3, 41.2, SiO2 24.0, Al2O3 13.07, FeO 11.23, Cr2O3 3.96, MgO 2.35, CoO 0.86, NiO 0.58, CaO 0.53, MnO 0.06. Sintering of Mikhailovskii ores and concentrates with the use of the pulp under laboratory conditions made it possible to increase the unit productivity of the sintering machine 2.9%, increase the impact strength of the sinter 4.5%, and increase its abrasion resistance 17.1%.
