Coal desulfurization by flotation method
IOP Conference Series: Earth and Environmental Science, 2023 Abstract In general, the combustion of coal containing high sulfur and ash causes negative environmental problems such as acid rain and the emission of oxides of sulfur. Coal flotation is one of the most effective methods for desulfurizing and deashing raw coal with high ash and sulfur contents before burning coal.
