“…Coal from deposits located in the eastern regions contains rare-earth and other components such as germanium, vanadium, chromium, gold, platinum, silver, titanium, and others, and in the case of some deposits the above are available in commercially significant concentrations [22][23][24]. Development of new technologies for the recovery of rare and rare-earth elements from coal and coal combustion products are subjects of numerous studies in many countries [25][26][27][28][29].…”

The coal industry in the eastern regions of Russia is of great economic and social importance. An analysis of the dynamics of coal deliveries from the eastern regions of Russia in 2010-2020 attested to a significant increase in exports while indicating reduced supplies to the domestic market. The eastern direction contributed most to the growth in coal exports. The eastern regions account for about 45% of Russia's coal balance reserves and have a significant potential for the expansion of mining the coal suitable for different uses: export, power generation, coke manufacturing and coke by-product recovery, and coal chemical industry. Based on the existing production capacity and coal mining development projects, the production of coal in the eastern regions is expected to reach up to 195-275 million tons by 2035 and its export volumes are estimated at 75-130 million tons. The expansion of coal supplies is influenced by a variety of factors, including the demand for coal; the condition and capabilities of transport infrastructure; the availability of coal balance reserves and production capacities; the decarbonization of the world's economies; geographical, climatic, geopolitical, and other conditions. The minimum levels of coal supplies correspond to their insignificant growth in the domestic market with moderate growth in exports, and the maximum levels correspond to the maximum possible growth of exports and the commissioning of coal-fired thermal power plants. The potential of the region to supply coal far exceeds the demand for it.

Gold-Bearing Brown Coal Deposits of the Zeya–Bureya Sedimentary Basin (East Russia): Fundamental Model of Formation

et al. 2021

The primary sources and the conditions for the formation of the Paleogene–Neogene coal-bearing deposits in the Zeya–Bureya sedimentary basin were identified and studied with the help of paleogeographic reconstructions and geochemical analyses. Based on the results obtained, we suggest a new basic model of element transfer into the coal, involving two mutually complementary processes to account for the introduction and concentration of gold and other trace elements in the sequences investigated. The first process reflects the system in which peatlands were concentrated along the basin’s junction zone and the passive internal residual mountain ranges. The second reflects the junction’s contrast-type (sharp-type) forms conditions along the external mobile mountain-fold frame. The eroded gold particles were transported over 10–20 km as complex compounds, colloids, dispersed particles, and nanoparticles, and remobilized into clastogenic and dissolved forms along the first few kilometers. The release of gold in the primary sources occurred due to weathering of gold-bearing ore zones, followed by transportation of gold by minor rivers to the areas of peat accumulation. This study considered the probability of the accumulation of high concentrations of gold and rare earth elements (REE) in coal due to the introduction of organic and inorganic materials during floods, with episodes of catastrophic events, and volcano–hydrothermal activities.

Major, trace, rare-earth elements, and noble metal have been analyzed from the brown coal of the Amur region (Russian Federation) and coal combustion products to understand the provenance and depositional environment. It was discussed that weathering crusts of ore deposits and host rocks located in the mountain-folded frame of the Zeya-Bureya coal-bearing sedimentary basin were the main source of mineral substance and chemical elements in brown coals. The distribution of minerals and elements inside the forming coal seams was influenced by the type of vegetation incorporated into coal-forming peat mires bog by catastrophic floods along the existed hydraulic network, the physicochemical parameters of plant debris transformation during their conversion to coal, as well as the sorption properties of inclusions and interlayer of bitumen and humic acids in coal beds. An experimental technological complex was created to study the microelements transfer process in the dust-gas stream and the distribution of rare earth and trace elements separately in varieties of coal combustion products (slag, fly ash, dustlike part of the dust-gas flow, and technogenic cleaning water). The resulting combustion products of coal have been studied by inductively coupled plasma (ICP)-spectrometry methods (ICPmass spectrometry and ICP-atomic emission spectroscopy). Sample preparation technique for analysis was improved to determine the elemental composition. It was established that more than 60% of trace and rare earth elements were concentrated in ash and sludge. Data on these
