  • Method for X-ray luminescent separation of minerals and X-ray luminescent separator
    Patent number: 9561528
    Abstract: The invention relates to the area of mineral processing, and more particularly to separation of crushed mined material containing minerals, which are luminescent under the action of exciting radiation, into products to be concentrated and tailing products. The invention can be implemented both in X-ray-luminescent sorters at all beneficiation stages and in product inspection devices, like diamondiferous raw materials testing.
    Type: Grant
    Filed: November 21, 2013
    Date of Patent: February 7, 2017
    Assignee: RESEARCH AND PRODUCTION ENTERPRISE “BOUREVESTINIK”
    Inventors: Leonid Vasilievich Kazakov, Natalia Pavlovna Kolosova, Pavel Nikolaevich Kuchin, Vladimir Iosifovich Tsvetkov

  • Method for separating minerals with the aid of X-ray luminescence
    Patent number: 8766129
    Abstract: The method relates to the field of mineral enrichment. It involves setting a threshold value for the intensity of a luminescence signal after a given time following the end of a pulse of exciting radiation, measuring, in the course of registering the intensity of the luminescence signal of a mineral, the intensity of the luminescence signal after a given time following each pulse of exciting radiation, recording the intensity value obtained for each luminescence signal if the signal registered exceeds the set threshold value, comparing the value measured in the current period with the values obtained in the preceding periods, determining the period in which the intensity value was at its peak, and processing the luminescence signal in which the value of the measured intensity was at its peak in order to determine the separation parameters; a decision to separate the mineral to be enriched is taken in the event that the separation parameters are inside the range of given values.
