The utility model relates to tailings disposal and particularly provides a tailings disposal plant, comprising a mud pump and a stirring device, wherein the mud pump is driven by a first motor; a sucker of the mud pump extends into a tailings pond; and the stirring device driven by a second motor is correspondingly arranged in a front-side area of the sucker. By arranging the stirring device at the front side of the sucker of the mud pump, waste ores with a large size can be stirred, so that the waste ores are dispersed to form waste ore slurry containing small-size waste ore blocks. Therefore, the ore slurry in the tailings pond can be continuously sucked through the sucker and the efficiency of the tailings disposal is improved. Additionally, the position of the stirring device can be adjusted by the tailings disposal plant disclosed by the utility model through a movable bracket, so that the stirring device can be matched with the sucker of the mud pump. Furthermore, the efficiency of the tailings disposal is improved.
