How Are Diamonds Processed? | Our Everyday Life

Once the concentrate is processed, it is then time to recover the diamonds. In most instances, the diamond concentrate will go through an X-ray sorter. Since diamonds fluoresce when exposed to radiation, sensors go off when flashes of light are thrown off by them. Once the light is detected, the diamonds are expelled from the process stream.
