“…A strong correlation of HREEs has been found with other trace elements, such as Ge, W, and Be, which were proven to be organically fixed, and a similar distribution pattern of REEs was found with Ge in coals as a function of particle specific gravity [25,28,[59][60][61].

Previous research indicates that coal and coal by-products are a potential source of critical elements including rare earth elements (REE) with estimated amounts in the range of 50 million metric tons. Despite the proven presence of elevated REE concentrations, commercial extraction and recovery have not been realized. This article provides a review of the abundance, mode of occurrence, and recovery methods of rare earth elements in coal and coal by-products. The feasibility of using established REE extraction and recovery technologies is discussed along with issues associated with their use with coal resources.

“…Rare earth elements (REEs) are a group of 15 lanthanide elements (atomic numbers [57][58][59][60][61][62][63][64][65][66][67][68][69][70][71] and two transition metal elements (scandium and yttrium) [1][2][3]. Promethium (Atomic Number 61) is extremely rare and is generally considered not to exist in nature [2,4].…”

“…In low rank coals, uranium is generally organically associated [13,[68][69][70][71]. Uranium-bearing minerals, i.e., pitchblende [45,[72][73][74][75], coffinite [30,45,49,72,73,76], and brannerite [30,76], were identified in coals.…”

Due to its environmental and resource impacts, the geochemistry of uranium in coal is of both academic and practical significance. In order to give a comprehensive summary about the geochemistry of uranium in coals, the abundance, distribution, and modes of occurrence of uranium in Chinese coals were reviewed in this paper. Although some coals from southwestern and northwestern China are significantly enriched in uranium, the common Chinese coals are of a comparable uranium concentration to the world coals. The roof and floor rocks, and parting of coalbeds, or coal benches that are close to the surrounding rock are favorable hosts for uranium in one coalbed. The uranium concentrations in coals of different ages decrease in this order, e.g., Paleogene and Neogene > Late Permian > Late Triassic > Late Carboniferous and Early Permian > Late Jurassic and Early Cretaceous > Early and Middle Jurassic. Uranium in Chinese coals is mainly associated with organic matter, and is correspondingly enriched in subbituminous coal and lignite.

“…Zilbermints et al [19] first reported Ge enrichment in coal. Subsequently, Hu et al [20], Wang [21], Seredin et al [16,22,23], Wu et al [24], and Hower et al [11] investigated the occurrence and distribution of Ge in Lincang (Yunnan, China), Wulantuga (Inner The sedimentary sequences in the Wulantuga high-Ge coal deposit include Silurian, Devonian, Permian, Late Jurassic, Early Cretaceous, Neogene, and Quaternary strata ( Figure 2), and detailed information of these strata has been described by previous studies such as Dai et al. [9], Du et al [10], Sha [40], and Li et al [31].…”

The mode of occurrence and origin of highly-enriched trace elements, especially Ge, in Wulantuga high-Ge coal deposit have been widely reported. In this study, coal samples and several coalified trunks embedded within the roof strata are collected, which provides a good opportunity to further confirm if Ge is mainly associated with organic matter. Minerals in coal samples are mainly quartz, kaolinite, montmorillonite, pyrite, and gypsum, along with trace albite, barite, chlorite, and Fe-oxide, while those in coalified trunk samples include melanterite, pyrite, and gypsum, with traces of chlorite and magnesiocopiapite. Germanium, As, W, Sb, Hg, Be, and Cs are enriched in coal samples, and these elements are also enriched in the coalified trunks and roof glutenite. The elevated contents of Ge, As, W, Sb, and Hg were almost exclusively derived from the influx of hydrothermal fluids as evidenced by the presence of pyrite veins and chamosite as well as enhanced elemental associations of Ge-W and As-Sb-Hg in the studied lignite samples. The coalified trunks in the study area should be taken into consideration due to the high contents of hazardous elements that cause potential environmental impacts during mining waste disposal and land reclamation.
