Limestone is the most important and abundant sedimentary rock and is formed by the compaction of the remains of coral animals and plants on the bottoms of oceans around the world. Limestone is composed of the mineral calcite (calcium carbonate) and/or the mineral dolomite (calcium and magnesium carbonate) along with small amounts of other minerals. There are three distinct types of limestone which are defined by their magnesium carbonate (MgCO3) concentrations:

  • Dolomitic limestone consists of 35 to 46% magnesium carbonate
  • Magnesian limestone consists of 5 to 35% magnesium carbonate
  • High calcium limestone contains less than 5% magnesium carbonate

Limestone is quarried or mined then crushed and screened to serve a wide variety of applications including:

  • pH adjustment (Ag-Lime, water treatment)
  • Formulated product filler (masonry cements, ready mix concrete, asphalt, and joint compounds)
  • Raw material in the production of glass, pulp & paper, portland cement and steel
  • Flue gas desulfurization
  • Production of stone blocks
