Operative control unit UOK-2 for checking of the intensity and kinetic features of diamonds and associate minerals luminescence is designed to determine the numerical values of luminescence features used in XRF sorters by Bourevestnik, Inc. in the course of sorting diamonds and associate luminescent minerals. Accumulation, backup storage, analysis and graphical presentation of data arrays are carried out. The features obtained can be used for the following:

• to analyze the preparability of diamond-containing materials by deposits and in the course of mining concrete deposits; 
• for optimum choice of sorting features put into sorters; 
• to control the operation of luminescent sorters.

The UOK-2 operation concept is based on the use of diamonds’ property of luminescence under X-ray impact and on the difference of those properties with diamonds and associate luminescent minerals. Option to simultaneously define the features when a luminescent object is detected, both from the radiation side and from the side opposite to radiation is implemented. The data obtained with the application of UOK-2 shall serve as a basis for upgrading XRF sorters as well as for upgrading enrichment process diagrams for diamond-containing materials.

UOK-2 includes a measurement unit (MU), a control and registration unit (CRU), and a PC with special software.
