Advances in the chemical leaching (inorgano-leaching), bio-leaching and desulphurisation of coals [PDF]
International Journal of Coal Science & Technology, 2019 Abstract Coal still remains an important source of power generation world over. Along with its usage, comes unwanted generation of noxious gas emissions, toxic metal releases into wastewater and other pollutants which ultimately lead to environmental concerns. So cleaning of coal through physical or chemical processes becomes utmost important.
