Dolostone (Limestone) - Arkansas

Limestone readily reacts with hydrochloric acid and produces carbon dioxide (CO2) as a gas. By contrast, dolostone is less reactive and normally must be in powdered form to react visibly. Pure dolomite contains 54.28 percent calcium carbonate and 45.72 percent magnesium carbonate. Dolostone is commonly referred to by its mineral name, dolomite.

Techniques for Determining Limestone Composition and Reactivity

Gypsum composition and purity are dependent upon limestone composition. When limestone possessing low available CaCO is fed to the system, limestone feed rates must increase to provide the same level of SO removal. In so doing, both limestone consumption and the level of impurities, including CaCO, within the slurry will increase.
