Processing Of Limestones

Limestone Mining - MSU Department of Geography

Lime is a mineral made by heating limestone or dolomite in a kiln. Lime is used in a variety of chemical industries, in sugar processing plants, in steel mills, sewage treatment plants, and at paper mills. "Burned" or kilned limestone was also used as plaster and mortar in the homes of early settlers, and even into the mid-20th century.

Limestone

The principal mineral of limestone is calcite (CaCO3), a form of calcium carbonate. Limestone is composed of material derived by both chemical and biological activities. Often, little distinction is made between limestone and dolostone because they are often interchangeable in their uses. Both are frequently sold under the name of limestone.
