To better understand the coal dust wetting ability of anionic surfactants with different
structures, sodium dodecyl sulfate (SDS), sodium dodecyl sulfonate (SDDS), and sodium …

Coal plays an important role in energy supply. However, low rank/oxidized coals are difficult
to float with the common oily collectors, and hence effective collectors are urgently needed …

Only when problems in ultrafine coal particle beneficiation process are well understood and
clarified, efficient methods can be devised to recover ultrafine coal particles in an …

As battery technologies evolve and the demand for sustainable energy solutions rises, the
request for natural graphite is expected to remain strong. The graphite used in battery …

The reuse potential for the large annual production of spent coffee grounds (SCGs) is
underexploited in most world regions. Hydrochars from SCGs produced via hydrothermal …

In the process of coal mining, storage, and transportation, the escape of coal dust restricts
