A method for treating tailing ores is characterized by comprising the steps of : introducing tailing ores which are generated in a wet beneficiation at a mining site and which are a high-moisture ultra fine iron ores having an average particle size of 10 µm or less directly to a mixing-agitation type pelletizer without conducting a drying treatment, conducting mixing-pelletizing at the mining site, transporting the granulated particles to an unloading port through a loading port and, thereafter, using the granulated particles of the tailing ores as sintering raw materials without conducting drying at the unloading port.
