PROBLEM TO BE SOLVED: To reduce an amount of disposal earth by effectively removing a fine particulate component attached to a coarse particulate component in slurry of the coarse particulate component and reducing moisture content of the coarse particulate component. SOLUTION: In this liquid cyclone 1, by applying centrifugal force to treating slurry by swirling the slurry A in a cylindrical part 2 having a hole 2a tapered toward the lower part, the slurry A is separated into coarse particulate component slurry B swirlingly falling along the inner peripheral face of the cylindrical part 2, and the fine particulate component slurry C blown up in the center of the cylindrical part 2. The coarse particulate component slurry B is discharged from a lower discharge part 4 provided at the lower end of the cylindrical part 2, and the fine particulate component slurry C is discharged from an upper discharge part 5 provided at the upper part of the cylindrical part 2. A washing means 7 is provided supplying at least one of washing water E and air D to at least one of the lower inside of the cylindrical part 2 and inside of the lower side discharge part 4 to remove the fine particulate component attached to the coarse particulate component of the coarse particulate component slurry B to wash the coarse particulate component.
