Disclosed herein is a metal sorting device including an X-ray tube (15), a dual energy detector array (4), a microprocessor (12), and an air ejector array (5). The device senses the presence of samples in the x-ray sensing regio and initiates identifying and sorting the samples (3). After identifying and classifying the category of a sample, at a speci time, the device activates an array of air ejectors located at specific positions in order to place the sample (3) in the prop collection bin (8 and 10).
