METHOD OF DRESSING OF EUDIALYTE ORES Russian patent published in 2014 - IPC B03B7/00 B03B13/06 B03C1/00

Abstract RU 2515196 C2

FIELD: mining.

SUBSTANCE: invention relates to the field of dressing of hard minerals, namely, to methods for enrichment of rare-metal ores. The method of dressing of eudialyte ores includes application of electromagnetic separation in intense field with separation of nepheline-feldspar concentrate into non-magnetic fraction and subsequent electric separation of magnet fractions with production of aegirine and eudialyte concentrates. In the head of the process they perform separation of ore with total secondary characteristic radiation Kα₁-series of elements of strontium, yttrium, zirconium and niobium in the energy range of 13.0-17.5 keV.

EFFECT: increased efficiency of extraction of eudialyte concentrate, reduced costs for grinding and crushing of ore, and also reduced quantity of cleaning operations.
