Diamonds emit light when hit by an x-ray and the resulting light is picked up by a detector. As a mono-layer stream of rocks and diamonds fall through this beam, the detector activates jets of air which knock the diamond into a separate bin (see figure 13). Variations of this principle are used on other mineral systems using lasers.
