It was founded in 1908 in Central Asia, in particular in Fergana Valley, in the deposits "Tuya-Moyin" and "Jil Bulak", rare metals mining - in addition to copper, radioactive chemical elements such as uranium, vanadium, radium, provided information about “Fergana rare metal mining society”. The charter of the “Fergana rare metal mining society” was also analyzed. “Fergana rare metal mining society” was founded by railway engineer Sergei Egorovich Palashkovsky and mining engineer Kh.I. Antonovich. During the “Fergana rare metal mining society’s existence from 1908 to 1918, the “Fergana rare metal mining society” mined 820 tons of ore, out of which 655 tons were shipped to St. Petersburg and uranium and vanadium preparations were processed and exported to Germany. In the 70s and 80s of the XIX century - early XX century, foreign investment was widely attracted, especially in the field of copper mining. The article analyzes the fact that the deposits in Fergana are one of the first uranium deposits in the Russian colony and have their own advanced experience.

Purpose. Study on the chemical composition of lake waters, salt brines, brine and bottom sediments to identify the mineralization of rare metals and other types of minerals. Methodology. Mass spectrometric studies (mass spectrometer with inductively coupled plasma ICP-MS 7500cx from AgilentTechnologies) for the purpose of high-precision analytical studies on the chemical composition of salt lake water in order to assess the content of rare elements. The use of unmanned aerial vehicles for linking and geometrizing lakes. Findings. Field surveys on the geometrization and linking of lakes were carried out. From the materials obtained with the help of the drone, orthophotoplans were created (with a measurement accuracy of up to 1 centimeter), as well as a digital terrain model and a digital terrain model. A complex of analytical works was carried out using inductively coupled plasma spectrometry. When analyzing the distribution graphs of the absolute content of micro-components in the waters of the lakes of the Delbegeteysky massif, it was found that all samples were enriched with sodium, phosphorus, iron, magnesium and barium. The results of the analyses revealed the predominance of sulfates and chlorides in the composition of the surface waters of most of the water bodies of the Delbegeteysky massif. At the Burabai site, lake waters are characterized by an alkaline reaction of the environment (on average = 8.71). At the same time, the salinity of water bodies varies from 05 to 9 g/dm3. Originality. Large-scale outcrops of granites of the Kalba complex (P1), with which a rare-metal type of mineralization is genetically associated, are known to be on the selected study sites. Quartz-wire-greisen and quartz-wire tin, tin-tungsten and tungsten formations are also widely developed. Considering the large geochemical migration ability of rare alkaline elements in the thickness of loose sediments as a result of intensive geodynamic processes in the East Kazakhstan region, it is possible to assume the possibility of their migration to the upper horizons and accumulation in salt lakes localized within the area of development of granite intrusions of Permian age and associated deep tectonic faults. Practical value. The results of the research can serve as a revival of the rare metal industry in the region, which will allow developing new high-tech industries and creating new jobs in this area. The obtained results can be used for setting up further exploration and operational work on the selected promising areas.

John Edmond was a geochemist the unifying theme of whose research was a quantitative understanding of the processes involved in the transfer of the chemical elements into and out of the oceans; in short, what controls ocean chemistry. He achieved this through oceanographic explorations sampling ocean waters for rare metals and explorations of hot springs on the deep sea floor, rivers from the Amazon to Siberia, and the rift valley lakes of Africa. This accompanied a strong background in chemistry and an almost reverent recognition of the value of data. John challenged established paradigms and pioneered developments in element and isotope systematics as applied to geochemical processes. He will alsobe remembered for his enthusiasm, his insight, his honesty, and his defence of anyone or any group he felt was badly treated.

The paper presents new geological, mineralogical, and isotope geochronological data for rare-metal pegmatites in the Kalba granitic batholith (Eastern Kazakhstan). Mineralization is especially abundant in the Central-Kalba ore district, where pegmatite bodies occur at the top of large granite plutons and at intersections of deep faults. The pegmatites contain several successive mineral assemblages from barren quartz-microcline and quartz-microcline-albite to Li-Cs-Ta-Nb-Be-Sn-bearing cleavelandite-lepidolite-spodumene. Ar-Ar muscovite and lepidolite ages bracket the metallogenic event between 291 and 286 Ma. The pegmatite mineral deposits formed synchronously with the emplacement of the phase 1 Kalba granites during the evolution of hydrous silicate rare-metal magmas that are produced by the differentiation of granite magma at large sources with possible inputs of F and rare metals with fluids.

Polymetallic Ore

We have examined tin-polymetallic ore, a complex mixture of cassiterite (SnO2) and sulfides, by micro-PIXE. Tin-polymetallic ore is one of the major sources of technologically important “rare metals”, especially of indium and bismuth, usually as trace elements. In addition to such rare metals, silver is another important trace component in the ore. But the trace elemental distribution of tin-polymetallic deposit has not well been described due to the small size of constituent minerals, complex ore texture, and lack of analytical method to detect trace elements in a small area. PIXE with a proton microbeam could be an effective tool to solve this problem by delineating the distribution of these trace elements among carrier minerals with the required sensitivity. Thus we have applied PIXE with the CSIRO’s proton microprobe to a tin-polymetallic ore from Canada. The result showed that micro-PIXE is an essential tool to study trace element distribution in such a complex ore.

The research determines the dynamics of gold mining and identifies the specifics of the development of the gold industry in Salair in the late XIX – early XX centuries. The Salair ridge was then under the jurisdiction of the Cabinet of His Imperial Majesty. At the end of the XIX century, the Cabinet spent a lot of money on geological survey of the ridge and invested in the development of the local gold mines. The extraction of gold during this period fluctuated within 6–8 poods (1 pood = 16 kg). At the beginning of the XX century, the Cabinet leased the Salair mines to private entrepreneurs and joint-stock companies. Such agreements were signed by Prince A. von Thurn und Taxis and Dr. Josef Jeanne (Austria), Arthur Stanley and mining engineer Farrukh Bek-Vezirov (Great Britain), State Councilor Berezin (Russia), and The Russian Gold Mining Company. Private companies operated more successfully than the Cabinet. In the XX century the extraction of gold in Salair increased. However, after the companies had developed the ready retrievable gold deposits, they ceased operating. As the calculations have shown, more than 3.6 tons of gold were mined on the Salair Ridge in 1892 – 1915. The main feature of the Salair gold mining was that gold was extracted both by the Cabinet and private companies, which means that state and private capital acted in parallel.

The results of the ore and accessory minerals study in the syenite of the Perga beryllium deposit are discussed. Phenakite and genthelvite are found among Be-bearing minerals. Genthelvite of this syenite, being compared to early published data on genthelvite of the Perga deposit, is distinguished by the highest ZnO content which is close to the theoretical maximum) due to the alkaline nature of studied rock ((Na + K)/Al = 1.09). Genthelvite occurs as later mineral to phenakite or is formed by phenakite replacement at rising the alkalinity as a result of melt differentiation. Columbite with high-Mn content, Y-silicate (keiviite-(Y)?), rare-earth fluorocarbonate (bastnesite) are also found among other minerals of rare metals. The presence of fluorite and rare-earth fluorocarbonate in association with genthelvite or phenakite may indicate that Be and REE were transported in ore-bearing fluids as complex fluorine-carbonate compounds. Considering the geochemical characteristics of rocks (meta-aluminous, subalkaline and alkaline series, deep negative Euanomalies, low Sr, Ba, elevated – HFS elements) from the Sushcano-Perga region, enrichment of these rocks with rare metals and Be are related to intensive feldspar fractionation of the primary melts and due to alkaline oversaturation, volatile and rare metals (Be, Li, REE, Y, Nb, Ta) enrichment in the residual fractions of granitic or syenitic compositions. Postmagmatic alkaline solutions enriched in F and CO32- promote of Be concentration in fluid phase with its following migration and crystallization as genthelvite.

Rare Metal Pegmatite

Rare-metal elements are strategic metals which, in general, are extremely important for economic development or maintenance of defence capability of any country at the modern level. The list of needs for these strategic metals ranges depending on the level of economic development of certain country, but in general it includes such elements as Li, Ta, Nb, Be, Sb, W, REE and others. The majority of these elements has the lithophilous nature and, therefore, is characterized by close genetic relations with granites and pegmatites associated with them. In the world, industrial production of lithium is shared between deposits to lithium-bearing brine of saline depositions of marine basins (Argentina, Chile), some granites (China) and rare-metal pegmatites (Australia, China, Zimmbabve). In pegmatites lithium mineralization is represented mainly by spodumene (LiAlSi2O6), But other lithium-containing metallic minerals can also play an important role in production of this metal – petalite (LiAlSi4O10), minerals of lepidolite (Sa [Li,Al]3[Si,Al]4O10[F,OH]2) and amblygonite-montebrasite (LiAlPO4 [F,OH]) series. Rare-metal pegmatite of Ingul megablock of Ukrainian Shield can be treated as unique (insufficiently studied in world practice) pegmatitic formations in which the main metallic mineral is represented by petalite. In metallogenic interpretations two ore districts can be distinguished within the megablok, that are specialized on rare metals (Li, Rb, Cs, Be, Ta, Nb, Sn) – Polohivka and Stankuvatka. Deposits and numerous ore manifestations of rare metals formed in rather similar geological and tectonic conditions and have many common features – both country rocks composition and mineralogic composition of ores. Within Ingul megablock (Shpola-Tashlyk rare-metal district) a number of lithium rare-metal deposits associated with pegmatites is discovered. In order to determine the age of lithium mineralization in granites of Lypniazhka, Taburyshche massifs and vein bodies of pegmatitic and aplito-pegmatitic granites, which are selected from different localities of this megablock, are dated by U-Pd isotopic method by monazites. It is established that emplacement of vein granites of Ingul megablock occurred within rather narrow age interval – 2040-2020 Ma and it is not significantly separated in time from formation of most granitoids they are spatially associated with. This fact, together with geological evidences, gives grounds to make the assumption that rare-metal lithium pegmatite are formed in the same age interval.

TiC based cermet is a candidate material for alternatives of WC-Co used in tools/dies. Ordinary, Ni and Co, etc. are used as a metal binder of TiC based cermet. They are kinds of rare metals, therefore it is desired that metal binders are also replaced with the ubiquitous materials. FeAl intermetallic alloys are one of candidate materials of alternative rare metal binder made from ubiquitous materials. FeAl is well-known as an extremely resistance material to corrosion under oxidizing atmospheres, sulfidizing atmospheres, and in molten salts. Combination of intermetallic and carbide, the hardness is very high, but it would be brittle. In this work, TiC-FeAl alloys are made by wet milling and pulsed electric current sintering to improve transverse rupture strength while the hardness is kept. We achieved that TiC-40 vol. % (Fe-40 at. % Al) alloy with hardness of 17.7 GPa and T.R.S. of 1.9 GPa.

1050 Aluminum Alloy

The influences of alloying elements Mg, Zn and Cu and rare metals Ce, Er and mix rare metal (MRE) on the hydrogen content and inclusion in 1050 aluminum alloy were studied by optical microscope, scanning electronic microscope (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). The results show that when adding 1wt.%Mg, 5wt.%Zn, 0.5wt.%Er and 0.5wt.%MRE into 1050 aluminum alloy, respectively, the decrements of density of the reduced pressure test (RPT) samples are 0.36g/cm3, 0.24g/cm3, 0.72g/cm3, and 0.24g/cm3, respectively. Mg and Er significantly increase the tendency of hydrogen adsorption in Al melt. The results of XRD analysis and microstructural observation indicate that the alloys adding Er contain more oxides and gas porosity.

Metasomatic Replacement

The Manitou Lake area (Kwyjibo and Lac Marmont sectors), located in Quebec's eastern Grenville Province, contains magnetite-rich deposits with variable morphological, mineralogical, and chemical characteristics. Most Kwyjibo sector deposits are rich in Cu, rare-earth elements (REE), Y, P, F, and Ag and are anomalous in Th, U, Mo, W, Zr, and Au, and Lac Marmont sector deposits are commonly poor in these elements. Deposits occur in or are closely associated with 1175–1168 Ma leucogranite. They contain combinations of magnetite, clinopyroxene, blue–green hornblende, titanite, apatite, fluorite, quartz, biotite, andradite, epidote, albite, hematite, sulfides (chalcopyrite, pyrite, pyrrhotite, molybdenite, sphalerite), ilmenite, allanite, and other REE-bearing minerals. Veins and breccias are common. Most of the magnetite mineralization was preceded by potassic metasomatism (microcline) and was followed by most of the sulfides and radioactive minerals. Nearby sulfide-dominant deposits may be related. The deposits were formed by metasomatic replacement and fracture filling from hydrothermal fluids of variable composition, which were probably channeled in major, active faults. Oxygen-isotope data from magnetite-rich rocks suggest that fluids were predominantly magmatic and (or) metamorphic and that, locally, mixing with cooler meteoric water may have facilitated precipitation of sulfides and rare-metal minerals. Titanites in mineralized rock have been dated at 972 ± 5 Ma, but most magnetite may be older. Mineralization was syn- to post-tectonic and occurred in an orogenic to orogenic-collapse setting. The Cu–REE–Y-rich deposits are similar to iron oxide – copper – gold (IOCG) Olympic Dam type deposits, and copper- and rare-metals-poor occurrences resemble magnetite ± apatite Kiruna-type deposits.
