Coal gangue (CG) can be a potential aggregate for concrete production considering its huge production. However, its porous structure and high water absorption significantly impact the workability of concrete, restricting its comprehensive utilization. This paper proposed a straightforward pre-soaking technique for CG, where the pre-soaked CG (PCG) is …

Coal gangue is a solid waste generated during coal mining and processing, accounting for approximately 10–20% of original coal production [].China, India, and the United States are the leading coal-consuming countries [].In 2021, over 50% of energy consumption in both China and India was derived from coal [].Notably, the cumulative stockpile of coal gangue …
Coal gangue, characterized by high ash content and low heating value, is an undesired but inevitable by-product of coal mining [[1], [2], [3]].Based on the fuel flexibility advantage of circulating fluidized bed combustion (CFBC) technology and increasing demand for electricity, coal gangue is widely used in CFBC power plants for power generation in some …
In mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals.
A. − GÉOL. Partie externe d'un filon métallifère, d'une nature différente de celle du gisement qu'elle enferme; en partic., enveloppe terreuse ou pierreuse d'un métal natif ou d'une gemme. Ce minerai, très-riche en fer, enfermé dans sa gangue fusible, convenait parfaitement au mode de réduction que l'ingénieur comptait employer (Verne, Île myst., 1874, p. 140).

Gangue, unwanted minerals in ore, is separated through processes like froth flotation, gravity concentration, or magnetic methods. Mineral processing involves liberation and concentration. …
Gangue is the unwanted impurities like rock material, dust, soil, sand, earthy particles, limestone, mica etc. present in an ore.
The remaining gangue, termed tailings, is potentially harmful and abundant, especially in lower grade deposits. Gangue and Tailings: Separating Value from Waste in Ore Processing. In ore processing, ores rarely consist solely of valuable minerals; they are often mixed with unwanted rocks and minerals, known as gangue.
Gangue is defined for the purposes of this report as being substances in a vein associated with the ore sought, which had no current value and were either raised and disposed or sorted …
