ent) gangue minerals, corresponding to their typical non-absorbing character (cf. § 1.2.2), in general allows them to be easily distinguished from ores (much higher R). As established …
As nouns the difference between cangue and gangue. is that cangue is a heavy wooden collar or yoke borne on the shoulders and enclosing the neck and arms, formerly used in china to punish petty criminals while gangue is (mining) the earthy waste substances occurring in metallic ore.
The mineral content of high alumina gangue clay is very high, and its main mineral composition is kaolinite. Kaolinite is a 1:1 type dioctahedral layered silicate mineral belonging to the triclinic crystal system, whose crystal structure (Fig. 1 a and 1b) consists of structural layers formed by joining of silica-oxygen tetrahedra and alumina-oxygen …

A metallurgical grade CMC used to depress Talc by rendering the surface of the gangue hydrophilic. Revadep 5050. Disperses fine material and depresses siliceous gangue such as quartz, mica, calcite and alumina-silicate. Revadep Cu++. A strong dispersant which alters the charge of fine gangue material, thereby repelling each other.
Coal gangue, produced during coal mining and processing [1, 2], is one of the most extensively produced solid wastes in China [1, 3], accounting for approximately 10%‒20% of raw coal production [].The accumulation of coal gangue causes serious environmental, social, and economic problems in the coal mining area [].Heavy metals …
Coal gangue is one of the largest mine solid wastes in China, and its discharge and stockpiling have caused resource waste, environmental pollution and other problems. Starting from the resource characteristics of coal gangue, this paper systematically discusses the ways and research status of coal gangue resource utilization, mainly …
Global rise in greenhouse gas emissions (GHG) is triggered mainly due to the consumption of fossil fuels for power generation and domestic usage. Among the fossil fuels, coal is a primary contributor to global GHG with substantial emissions generated during its mining and combustion process. Coal gangue, a residue produced during the …

1. Introduction. As a significant energy source in the world, coal accounting for more than 27% of the primary energy structure [1], [2], and is widely employed in daily production and life.Gangue is a low-carbon solid waste produced during coal mining and washing, accounting for about 10%−15% of the total coal output [3].The cumulative …
The cemented coal gangue backfill (CGB) in coal mining is normally made of gangue (particle size of 0–15 mm), fly ash, cement, and water. In this study, the effects of the weight content (ranging from 20% to 60%) of fine gangue (0–5 mm) on the microscopic characteristics, resistivity, and compressive strength of CGB were investigated at …
The precise identification of damp, sticky coal gangue; efficient jet nozzle separation; and process layout in a narrow, restricted space are essential technologies for gangue source reduction based on underground gangue photoelectric separation, which is critical for the long-term growth of coal mines. In this paper, the X-ray absorption fine …
Coal gangue is one of China's main industrial solid wastes, which contains various harmful heavy metal elements, such as lead (Pb). The long-term accumulation of coal gangue causes Pb to migrate to the surrounding environment due to weathering and rain erosion, eventually endangering human life and health with its continuous …

Sun et al. [24] activated a mixture of coal gangue and straw in KOH and H2O2 solutions to prepare silicon fertilizer, but the Si that was finally available in the activated coal gangue was only approximately 1.0–3.5%; it is thus dificult to prepare high-eficiency silicon fertilizer using chemical activation.
