INCINERATED-ASH TREATMENT DEVICE AND TREATMENT METHOD
[OBJECT] To efficiently recover noble metals such as gold, silver and copper and aluminum from incineration ash, and effectively use ash after recovering the noble metals and others.[MEANS OF REALIZING THE OBJECT] An incineration ash treatment apparatus 1 including: a crusher for crushing an incineration ash A1 to be less or equal to 5mm in maximum particle diameter, or/and a classifier for classifying an incineration ash to obtain an incineration ash whose maximum particle diameter is less or equal to 5mm; an eddy current separator 8 for separating an incineration ash whose maximum particle diameter is less or equal to 5mm discharged from the crusher or/and the classifier into a conductor E and a nonconductor I; a specific gravity separator for separating a conductor discharged from the eddy current separator 8 into a high gravity material H2 and a low gravity material L2. The specific gravity separator can be an air table 10. A classifier for classifying a crushed material C, classifying point of which is 5mm or less, can be mounted, and fine particles P whose particle diameters are 5mm or less discharged from the classifier can be fed to the eddy current separator 8. Rotation speed of a drum of the eddy current separator 8 can be 4000rpm or more.
