1. Introduction. Coal gangue is a solid waste discharged during coal mining and coal preparation processes. It is typically a black-gray rock with a low carbon content, harder than coal, and is associated with the coal seam during the coal formation process (Li et al., 2018; Sun et al., 2020).Its annual output accounts for approximately 15%–20% of …
Abstract China launched the Deep Resources Exploration and Mining (DREAM) program in 2016. Since then, the program has made significant progress in the exploration of critical minerals, such as rare earth, rare, and rare scattered metals. A "five-in-one" model, based on climate, landform, parent rocks, carrier minerals, and pH values …

Proceed to the next step, these studies have profound theoretical significance and fremendous economic significance to find and …
Gallium is won as a by-product from both zinc and alumina production (Jaskula, 2015a), the latter being the most important source.Since the value of gallium contained in the corresponding ores is small compared to that of the main product (e.g. Wellmer et al., 1990; Andersson, 2000), the capacity for gallium production is ultimately …
This U.S. Geological Survey (USGS) data release provides the descriptions of the only U.S. sites—including mineral regions, mineral occurrences, and mine features—that have reported production and (or) resources of gallium (Ga). The sites in this data release have contained resource and (or) past production of more than 16 metric …
A superlarge gallium ore deposit in Jungar, Inner Mongolia has been reported (Dai et al., 2006a, 2006b). In other cases, Ga concentrations of some coals are much higher than the industrial grade but Ga locally enriched in these coal seams in many Permo-Carboniferous coalfields (Zhou and Ren,1981; Li, 1991; ...

A preliminary estimation showed that the ensured and prospected reserves of Ga in No.6 Coal are up to 6.3 104t and 8.57 15t, indicating a superlarge gallium ore deposit.
metal-polymetallic sulfide ore deposits that are cogenetic with peat coal and black shale, some of which, e.g. the Xinhuang barite deposits in Hunan Province, can be regarded as large or superlarge in terms of scale. In addition, many phosphate deposits in large to superlarge scale in Yunnan and
Concerns over the future availability of gallium are due particularly to its importance in the production of thin-film photovoltaics (e.g. Fizaine, 2013). Gallium is won as a by-product from both zinc and alumina production (Jaskula, 2015a), the latter being the most important source. Since the value of gallium contained in the corresponding ...
Furthermore, Qin et al. (2009) predicted 16 super-large and 6 medium-sized potentially economic Ga-enriched coal deposits based on measured data from 5079 …

This paper discusses the rare earth elements in the No. 6 Coal (Late Carboniferous) in the Heidaigou Mine of Inner Mongolia, northern China. The results show that the vitrinite reflectance (0.57%) is lowest and the proportions of inertinite and liptinite (32.4% and 5.4%, respectively) in the No. 6 Coal of the Heidaigou Mine are highest …
Abstract Gallium (Ga) and aluminum (Al) belong to group IIIA elements in the periodic table. They show a coupled geochemical behavior in most natural systems and are considered as "geochemical partners." However, compared with the principal oxyhydroxides of Al in nature, gibbsite [Al(OH)3], boehmite (γ-AlOOH), and diaspore (α-AlOOH), only …
Abstract: The concentration, modes of occurrence and geological origin of beryllium in five workable coal beds from the Pu'an Coalfield of Guizhou were studied using the inductively coupled‐plasma mass spectrometry (ICP‐MS), floating and sinking experiments (FSE) and sequential chemical extraction procedures (SCEP). The results …
The crude reserve estimate of gallium resources in central China is approximately 10.06 × 10 4 tons, corresponding to a super-large coal-hosted gallium …
Our results show: (1) Gallium is significantly enriched in the coal seams from the study area, with an average content of 18.8–26.0 ppm. Gallium is distributed heterogeneously in the coals, and reaches ore-forming scales only in No. 6 coal of Heidaigou Surface Mine, not in the other mining districts of Jungar Coalfield. (2) On the horizontal ...
The tuff, a part of coal-bearing strata, in the Zhongliangshan coal mine, Chongqing, southwestern China, hosts a rare metal deposit enriched in rare earth elements (REE), Ga and Nb. However, the extraction techniques directly related to the recovery of rare metals in coal-bearing strata have been little-studied in the literature. The purpose of …
