PROBLEM TO BE SOLVED: To provide a mill pyrite feed treatment method capable of making it unnecessary to individually providing piping for feeding the pyrite discharged from a mill under pressure and piping for feeding bottom fly ash of a coal burning boiler as a slurry up to a disposal place such as an ash dumping ground or the like as separate systems to achieve sharp cost reduction, and equipment. SOLUTION: The clinker discharged from the coal burning boiler 30 is fed to a clinker crusher 32 to be ground and the ground clinker is supplied to a bottom ash bin 34 through a charging means 33 to be stored as bottom ash while the pyrite discharged from the mill through the pyrite hopper 19 of a pyrite discharge device 2 is supplied to the bottom ash bin 34, in which the bottom ash of the coal burning boiler 30 is stored, by a forced-feed means 35 and the bottom ash and pyrite stored in the bottom ash bin 34 are together fed to the disposal place such as the ash dumping ground or the like as the slurry by a slurry feed means 36.
