Lime Kiln Dust

Graymont's operations produce lime kiln dust, commonly referred to in the industry as LKD, as a byproduct of the lime-manufacturing process. LKD is a very fine-grained material, especially useful for applications requiring very small particle size. LKD applications are wide ranging, including soil reclamation and agriculture.

Hydrate Tailings

Lime material remaining from the manufacture of hydrated lime is called hydrate tailings. This material is used in a number of industrial processes.

Baghouse Lime

Baghouse lime is similar to lime kiln dust. The material is extremely fine-grained and is used in a variety of applications.

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.
