The intellectual features of beneficiation equipment become increasingly prominent and efficient upgrading of intelligent beneficiation equipment technology is one of the effective ways to improve beneficiation efficiency. In this paper, it is systematically introduced the development process of photoelectric intelligent sorting technology in the field of beneficiation and its application progress in multi ore sorting. Moreover, it is introduced and analyzed the working principles and technical performances of XRT intelligent sorting machine. Finally, it is introduced the experimental study of pre-separation for iron bearing rock of an iron ore with photoelectric intelligent sorter. The results showed that the rough concentrate with the iron grade of 25.13% and recovery rate of iron of 67.98% could be obtained by discarding the tailings with the iron grade of 9.53% and productive rate of 55.39% under the condition of the raw ore with the particle size of 10~100 mm and iron grade of 16.49% so that the expected indicators could be achieved, which provides scie.pngic basis for the resource utilization of iron bearing rock and the further popularization and applications of the equipment.
