The invention provides a method for manufacturing a metallurgic composite pellet by using different binders and a two-step pelletizing way. The method comprises the steps: with an inorganic binder as the binder of a pellet core, preparing the pellet core through disc pelletizing or pressure pelletizing, wherein the diameter of the pellet core is 2-8mm, and the addition amount of the inorganic binder is 0.5-3.5%; with an organic binder as the binder of a pellet shell, attaching an iron-contained raw material onto the pellet core through disc pelletizing or pressure pelletizing to obtain the pellet with the diameter of 8-15mm, wherein the iron-contained raw material contains 0.1-1.0% of organic binder, and the volume ratio of the pellet core to the pellet shell of the obtained pellet is 1:1 to 1:4. Compared with a pellet with the inorganic binder, the pellet prepared by using the method provided by the invention has higher fresh pellet falling strength; in addition, the organic binder at an outer layer burns and decomposes in a roasting process, so that the iron grade of the pellet placed into a furnace is relatively high; compared with a pellet with an organic binder, the pellet prepared by using the method has higher compressive strength. All metallurgical performance indexes of the composite pellet are greatly superior to those of a conventional pellet, so that a relatively considerable economic benefit can be created.
