The investigation of main ore-forming minerals of Anadol ore occuarence was performed by different methods: X-ray diffraction and electronic microprobe analysis, optical and electronic microscopy. The results showed that the concentrators of rare-earth elements (REE) was minerals of different classes - allanite, cerite (silicates), britholite (silicophosphate), bastnaesite (carbonate), monazite (phosphate), cerianite (oxide). However anymore 98% from the most quantity of REE concentrated in silicates, thus 90% - in allanite. Research of the fluid inclusions showed that Anadol ore occuarence had been formed in a wide temperature range - less than 850 to 130-170 Celsius degree. The results of researches can have practical application: а) development of flowsheet of REE extraction from ores Anadol type necessary take into account, that the minerals-concentrators are belongs to the different classes; б) almost complete absence of radio-active elements in allanite and allanite ore can apply them in metallurgy of alloyed steel.
