CEO
RedZemTekhnologii LLC
RedZemTekhnologii LLC, established in 2012, is specialized in the mining and primary beneficiation of thorium-bearing ores, with its resource base located in the Ural region of Russia. The company currently holds 80,000t of monazite concentrate. RedZemTekhnologii LLC possesses all the necessary licenses and official permits issued by Russian state authorities, allowing it to fully comply with applicable regulations for export operations and to arrange international shipments of monazite concentrate.
Asian Metal: Hello, Mr. Sergeyev. Welcome to our interview section at Asian Metal. Could you briefly introduce your company and core business?
Dmitriy Sergeyev: RedZemTekhnologii LLC is a Russian company founded in 2012. We specialize in the mining and primary beneficiation of thorium-bearing ores. Our headquarters is located in Moscow, and our resource base is in the Ural region. We currently hold 80,000t of monazite concentrate, which is one of the most critical feedstocks for the global production of rare earth oxides. We operate a dedicated production and logistics complex that serves as a hub for storage, repackaging, and shipment preparation for end users. I would like to emphasize that RedZemTekhnologii LLC holds all the necessary licenses and permits issued by Russian state authorities, enabling us to fully comply with relevant regulations for export and international transportation of monazite concentrate.


Asian Metal: What are the typical contents of praseodymium, neodymium, lanthanum, and cerium in your monazite concentrate?
Dmitriy Sergeyev: According to laboratory test results, the average rare earth composition of our monazite concentrate is as follows: praseodymium 2.5%, neodymium 8.0%, lanthanum 10.5%, and cerium 20.5%. The average total rare earth oxide (TREO) content is approximately 53.7%.
Asian Metal: What kind of buyers or partners are you looking for?
Dmitriy Sergeyev: We are customer-oriented and are open to cooperation with any partners interested in procuring our monazite concentrate. However, due to the specific nature of monazite materials—which contain naturally occurring thorium and uranium impurities—any potential buyer must possess the necessary import permits issued by the competent authorities of the destination country, in accordance with international regulations and IAEA guidelines, in order to proceed with shipments of monazite concentrate.
Asian Metal: Could you give us an overview of monazite resource distribution and mining activity in Russia?
Dmitriy Sergeyev: Russia has abundant reserves of monazite-bearing ores. As early as the 1940s and 1950s, during the Soviet era, the country conducted extensive geological exploration of monazite placer deposits to build a domestic raw material base. During that time, more than 100 commercially viable monazite-rich deposits were discovered across the country. Preliminary mining activities were launched, and long-term stockpiles of monazite were established. At present, there is no active monazite-specific mining in Russia, primarily due to the large volume of existing stockpiles. Today, monazite is typically recovered as a byproduct from the processing of titanium ores, ilmenite-zircon sand, or traditional gold mining tailings. The monazite concentrate stored in our long-term facilities is an intermediate product obtained through mechanical beneficiation of monazite sands extracted from various deposits during the Soviet era. Based on our internal assessment, Russia’s cumulative monazite reserves exceed 80,000t, most of which were accumulated during Soviet mining operations. These reserves provide a solid foundation for future processing and potential export.
