METHOD OF SEPARATION OF MINERALS Russian patent published in 2007 - IPC B07C5/342 

FIELD: enriching or classifying of materials.

SUBSTANCE: method comprises transporting minerals as a multi-layered system, affecting the minerals by penetrating radiation that excites luminescence, recording light beam of luminescence from the side of penetrating radiation and from the opposite side, and separating the mineral comparing the results with a reference value. The transparency of mineral is additionally determined. The minerals are separated according their transparency to the penetrating radiation. The transparency of mineral is determined from the difference of logarithms or from the logarithm of the ratio of the light beams of mineral luminescence from the side of the exciting flux to that from the opposite side.

EFFECT: improved quality of separation.
