Abstract
Finely divided limestone is produced by abrasively grinding limestone in an aqueous media in the presence of added dissolved carbon dioxide or in the presence of a soluble acid-forming compound, the anion of which forms a soluble calcium compound, or in the presence of both dissolved carbon dioxide and an acid-forming compound. The finely divided limestone is used in a dry flue gas desulfurization process.
