  • Coal desulfurization and demineralization by chemical Coal desulfurization and demineralization by chemical

    mineral matter is removed from the coal and the sulfur content greatly reduced. In some cases coal with a large ash content was precleaned by physical methods to remove part of the ash-forming mineral matter and thereby reduce the burden on chemical leaching. To better understand the behavior of mineral matter in this process
