In the diamond industry separation equipment is widely used based on radiometric methods for enrichment of diamond materials. Among this equipment, X-ray luminescence sorters are most widely used.
The X-ray luminescence sorters operating principle is based on the property of diamonds to luminesce under X-ray radiation and on contrast nature of diamonds x-ray luminescence generated from accompanying minerals luminescence.
Advantageous of X-ray luminescence sorters in comparison, for example, with equipment based on gravity or viscosity separation methods are as follows:
• Higher selectivity;
• High percentage of diamonds recovery;
• Low operational costs;
• Noticeably less environmental impact.
Bourevestnik, Inc. is rich in traditions of X-ray luminescence sorters development and manufacture, starting with the first industrial prototype in the world of the X-ray luminescent sorter LS-20 for the diamond industry, made in 1969.
By now more than 1600 sorters have been produced and 600 of them are in operation.
