Our Company carries out the processing of fluorite ores into a sellable concentrate for the
needs of the metallurgical industry, although possibilitiesfor the production ofacid grades
concentrate are currently being considered. The main problem that many consumers of fluorite
concentrate of metallurgical grades (FK-75, FK-85, FK-92) encountered in recent years is the
extremely low quality of the supplied products.
The depletion of fluorite reserves on the territory of Mongolia (the main supplier of this
raw material to the Russian market), handicraft methods of extraction and processing of
fluorite ores by the producers of this country, the prevalence of manual labor during extraction,
which excludes the possibility of the delivery of uniform quality raw materials, lack of
investment in geological exploration –those are the main reasonswhy the quality of fluorite
supplied to the market of our country is constantly decreasing. It should be noted that the
process is avalanche-like, and in the foreseeable future the situation will only worsen.
Occupying today the third place in the world for explored and confirmed fluorite reserves,
Russia is 100% dependent on imports of this raw material from the Mongolian People's Republic,
and is a hostage to the problems of the mining industry in Mongolia. Intending to rectify this
imbalance, our company takes part in several projects, the purpose of which is to reanimate
the production of fluorite on the territory of the Russian Federation and offer domestic
consumers a quality concentrate for the needs of metallurgy and the chemical industry.Having
considerable experience in the field of design and development of technologies for ore mineral
treatment, the specialists of our company have developed a unique technology for the enrichment
of fluorite ores, with the use of world-leading know-how and technical solutions. Enrichment
of fluorite ores with the release of the metallurgical concentrate FK-75, FK-85, FK-92 in
accordance with GOST 29220-91 as a finished product is produced due to a fully automated
separation of the useful component of CaF2 (actually fluorite) and the host rock with zero
content of the useful component .
For the separation of CaF2 and the host rock, a pre-selected separation feature is used.
In our case, this ability of fluorite to luminesce, which allows us to apply the widely
known method of X-ray fluorescence separation. The process for obtaining the sellable
fluorite concentrate is the following: the ore mined in the quarry with a low content
of C aF2 (from 20% to 45%) passes through a stage of ore preparation, on which the ore
is crushed and screened. Further, after passing the stage of ore preparation, the intermediate
industrial product (divided by the appropriate classes of size) is sent to the mobile
enrichment complex (separator).
Changing separator settings allows you to control the fluorite content in the final product,
and to obtain metallurgical concentrate with any given fluorite content. With a CaF2 content
of 25-30% in the initial ore, a metallurgical concentrate with a final CaF2 content of 65%,
75%, 85%, 92%, and in some cases a concentrate of higher grades can be obtained at the outlet.
As a by-product of production, fluorite screenings (a size class from 0 mm to 10 mm) with
a CaF2 content of 40% to 65% are formed. This product is actively used in the production
of cement, and is shipped to these enterprises. At present, the specialists of our company
have launched a pilot project for processing and enrichment of fluorite ores at one of
the deposits in the Chita region. Monthly ore processing volumes are from 5,000 to
10,000 tons per incoming ore. The volume of finished products - from 1,700 to 3,500
tons of fluorite concentrate brands FK-75, FK-85, FK-92.
