A system for detecting and discriminating a metal object in a bulk non-metallic material includes at least one triple-axis magnetometer adapted to detect a change of a magnetic field and output a signal including a detection signal representative of a metal object and a signal processing system adapted to detect the detection signal. The bulk non-metallic may be continuously moving through a detection volume, or may be placed in and removed from the detection volume as a batch. |
