The invention relates to the technical field of mineral sintering, and in particular relates to a method for manufacturing sinter. The method comprises the following steps: crushing a raw ore, and screening by utilizing a first screen, wherein the screen underflow is a first raw ore, and the screen overflow is a second raw ore; preparing a sintering material; conveying the sintering material to a primary rotary drum mixer, and adding a water wetted sintering material; uniformly mixing the sintering material, conveying the mixture to a second rotary drum mixer, and granulating; uniformly spreading the granulated sintering material to a trolley of a sintering machine; igniting the sintering machine to burn the sintering material, and controlling the negative pressure of sintering to be 9,000-18,000Pa; and cooling the sintered sintering material, and screening the cooled sintering material by adopting a second screen, wherein the screen underflow is a sinter return ore, and the screen overflow is finished product sinter. According to the method for manufacturing the sinter, the raw ore can be appropriately applied, the sinter components are stable, and the ore preparation cost is reduced.
