Incinerated-ash treatment device and treatment method
An apparatus and method 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. An incineration ash treatment apparatus 1 including: a crusher for crushing an incineration ash A1 to be less or equal to 5 mm 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 5 mm; an eddy current separator 8 for separating an incineration ash whose maximum particle diameter is less or equal to 5 mm 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 5 mm or less, can be mounted, and fine particles P whose particle diameters are 5 mm 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 4000 rpm or more.
