The invention discloses a limonite sintering treatment method which comprises the following steps: baking limonite, adding a sintering mixture, and sintering, wherein combustion blast furnace gas is used for baking the limonite, the baking temperature is 410-460 DEG C, and the baking time is 6-10 minutes. The limonite power is mainly composed of the following components in percentage by weight: 37.7-43.66% of TFe, 18.3-23.6% of SiO2, 0.1-0.5% of CaO, 0.3-0.6% of MgO, 4.3-5.6% of Al2O3 and 10.7-12.8% of Ig. Compared with the prior art, the method disclosed by the invention can eliminate the blowout phenomenon of coarse-grain limonite in the sintering process, enhances the strength and yield of the sintered ores, reduces the limonite crystalline water content and fuel consumption, is beneficial to sintering, can improve the metallurgical properties of the sintered ores, enhances the technical economical indexes of blast-furnace smelting, and greatly enhances the resistance to tumbling, yield and metallurgical properties of the sintered ores.
