A method and a sorting installation for segregating mineral-containing objects or plastic objects from a single-layer stream of material are presented. It is thereby provided - that objects (12) in the stream of material are irradiated with excitation light and the resultant fluorescent light is detected in the form of an imaging of the fluorescent locations, - that the objects in the stream of material are irradiated with object detection light outside the fluorescent light and the transmission light after passing through the objects or the reflection light from the objects is detected in the form of an imaging of the individual objects, - that an object is then defined as containing at least one particular mineral or one particular plastic if fluorescent light of this object lies in a predetermined intensity range for at least one predetermined wavelength range, and - that objects defined in this way are separated from other objects in the stream of material. |
