A glass cullet separation apparatus according to the present invention includes a hopper (1), a rotary feeder (6), an inclined guide plate (14), a conveying belt (17), and a foreign glass discrimination device (37). The discriminated device can radiate a laser beam onto a surface of a cullet passing over a slit of the conveying belt (17) for emission therefrom and for discriminating a "yes or no" foreign glass determination by analyzing a spectrum of the emission. Also, included is a color discrimination device (41), a foreign glass discrimination trigger sensor (33), a color discrimination trigger sensor (40), and air nozzles (44) for ejecting the cullet at each predetermined positions which correspond to the cullet of the foreign glass and the cullet of each color. A non-contact type photoelectric sensor (45) is provided for sensing the cullet passing the air nozzle (44). A collection receptacle (42) is provided for collecting the cullet, and a control device (28) is provided for controlling opening and closing of an electromagnetic valve of the air nozzle (44) for ejecting the cullet in response to a predetermined signal.
