Pulverized Limestone Products

Pulverized limestone products are produced by grinding and screening industrial-grade limestone and dolomite.


These products are used in a variety of applications including:

  • Mining - rock dust is used to suppress coal-dust explosions.
  • Agriculture - to neutralize soil acidity, increase plant nutrients, increase organic matter, enhance soil organisms and increase trace elements.
  • Exhaust-gas scrubbers - in industrial and power plants.
  • Scrubber reagents - for sulfur removal in circulating, fluidized bed boilers.
  • Roofing materials - as a filler in asphalt shingles.
  • Drilling mud additives - an essential component in drilling mud.
  • Glass stone - a primary ingredient in the glass-making process.
  • Feed supplements - provides essential minerals in animal feed.

After processing, products derived from limestone can eventually revert to their original chemical form by reacting with carbon dioxide in the atmosphere or from industrial processes.
