Claim 1:
2. A using method for an additive for reducing a roasting temperature of fluxed magnetite pellets according to claim 1, comprising following steps: mixing magnetite concentrate, bentonite, calcium flux, and the additive into a mixture, then adding water accounting for 12-14% of a dry base mass of the mixture, preparing a same into green pellets with a diameter of 10-12.5 mm in a disc balling machine, preheating the green pellets at 600-1000° C. for 15-20 minutes after completion of drying the green pellets to ensure that Mn2O3 is fully decomposed, then roasting a same at 1200° C. for 15 minutes, and after roasting, cooling the pellets to a room temperature to obtain finished pellet ore.
