How do we separate ores from waste? Naked Science Forum

Aug 08, 2012· Most diamonds fluoresce under X-Rays, so some mines crush the ore and run it under an X-Ray tube. Cameras detect the glow, and the diamonds are separated into a different stream by blasts of air. This sure beats one old-time method, where a diamond deposit in a sandy desert was mined by paying the locals to lie down on their stomachs in the hot
