This article presents an extensive review of the coal-agglomeration process, including oil-
agglomeration theory, characterization methods of coal hydrophobicity, and the main factors …

Activated carbon (AC) was prepared from low rank Rawdon coal by chemical activation. The
raw and demineralised coals were employed to produce ACs. The effects of …

The cleaning potential of a low-rank lignite coal has been evaluated via dense medium
separation (DMS), Reichert spiral and flotation techniques. The washability characteristic of …

The association of mineral matter with organic matter is extremely important for coal
utilization process such as pf coal combustion. With the development of advanced analytical …

Experiments were carried out with waste phosphors collected during the recycling of end-of-
life fluorescent lamps to obtain a highly enriched phosphors product as starting material for …

Dense medium separation (DMS) is a technique used to separate particles based on
specific gravity. Conventional DMS is, however, limited to coarse particle sizes and is not …

Spherical oil agglomeration of bituminous coal fines was carried out using diesel oil as a
bridging liquid. The effects of parameters, such as the dosage of bridging liquid, the solid …

Coarse particle gangue rejection is highly topical due to the potential benefit in removing a
significant fraction of gangue prior to fine grinding, thereby creating significant potential …

Oil agglomeration is a surface property based on the differences in the surface properties of
the organic and inorganic constituents of coal. A bituminous coal was agglomerated using …

The combustion of some types of biomass leads to the formation of ash deposits, which
reduce the efficiency and reliability of boiler equipment. The mechanism of formation of …
