METHOD OF MAKING PELLETS FROM ORES AND CONCENTRATES OF FERROUS METALS Russian patent published in 2013 - IPC C22B1/243 C22B1/244 

Abstract RU 2484151 C1

FIELD: metallurgy.

SUBSTANCE: proposed method comprises mixing polydisperse ores of ferrous metals and/or concentrates of ferrous metal ores with binder and mix pelletising at pressure. Note here that said binder represents solution of carboxymethyl cellulose of 1-3 wt % concentration in amount sufficient to get mix with moisture content of 7-14% and with addition of bentonite in amount of 0.2-1% of polydisperse material weight. Obtained pellets are roasted at 900-1300°C.

EFFECT: simplified process, higher strength, water resistance and dilution.
