The invention relates to a method for using paigeite powder in sintering, and belongs to the technical field of iron ore powder sintering. The method comprises the following steps of: preparing raw materials, mixing, granulating, distributing the raw materials, igniting, sintering, crushing, cooling, and detecting indexes of sintered ore. The iron-containing raw materials of the sintered ore comprise 8 to 12 percent of paigeite, 4.5 to 5.5 percent of calcined lime, 1 to 3 percent of dolomite, 5 to 7 percent of limestone and 4.0 to 5.0 percent of coke powder; and the alkalinity CaO/SiO2 of thesintering ores is equal to between 1.8 and 2.0, TFe content in the sintered ore is between 55 and 58 percent, MgO content in the sintered ore is between 1.9 and 2.3 percent, and FeO content in the sintered ore is between 6.0 and 7.5 percent. In the method, local powder (or Australian fine powder) and a MgO mass fluxing agent (such as the dolomite) are replaced by the paigeite powder simultaneously, so the paigeite powder can be used reasonably, the total proportioning of the fluxing agent is reduced by 10 percent, the quality of the sintered ore is improved, and the concept of concentrates ismet.
