METHOD FOR RADIOMETRIC CONCENTRATION OF MINERAL RESOURCES Russian patent published in 2005 - IPC

FIELD: concentration of mineral resources.

SUBSTANCE: method includes irradiation of source material during its displacement through control area in piece-wise mode by x-ray radiation. Characteristic roentgen-fluorescent radiation is recorded for at least one of controlled components and size of controlled piece is determined. Concurrently within limits of same control zone roentgen-luminescent radiation of controlled components of source material is recorded. Source material is separated in accordance to separation criteria set for both recorded radiation and set limits of separation. Source material can be separated on three products. As source material following substances can be used: diamond-containing resource, wherein controlled components are diamond and kimberlite or diamond and accompanying minerals - calcite, zircon; manganese ore, where controlled components are manganese and apatite, as well as manganese ore, where controlled components are manganese and calcite; tungsten-molybdenum ore, where controlled components are tungsten and molybdenum; scheelite ore, wherein controlled components are scheelite and rock, containing luminescent materials.

EFFECT: higher efficiency.
