Abstract: An apparatus for bulk ore sorting using gamma activation analysis is disclosed. The apparatus includes a conveyor system that includes one or more conveyor belts, surrounded by one or more radiation shields, to transport ore material along a transport path. A pulsed X-ray radiation source is configured to irradiate ore material at an irradiation region and one or more detectors are configured to detect a gamma radiation output from irradiated ore material at a detection region. The transport path has a bend, located between the irradiation region and the detection region, and about a vertical axis, of at least 45 degrees. The one or more detectors are configured to detect a radiation output from the irradiated ore material at times between X-ray pulses of the pulsed X-ray radiation source irradiating the ore material.
