Specialty Minerals Building Product Limestones in the Western United States—Lucerne Valley, California

A broad range of ground calcium carbonates (GCCs) are produced for the building products industry in the Western U.S. by Specialty Minerals Inc. (SMI) at its plant in Lucerne Valley, California. The high-quality limestone deposit there has been mined since the mid-1800s, with finely ground industrial products manufactured since 1961.

The high-brightness and high-purity limestones from Lucerne Valley are used in many building products, such as roofing, flooring, tape joint compounds, cast polymers or cultured marbles, stucco, and cement and masonry, as well as in such other applications as plastics, coatings, rubber, caulk and sealants and gel coats.

Lucerne Valley’s fine-ground, bright-white Vicron® GCC family of 2 to 13 micron products and Marblewhite® GCC family of 30 to 325 mesh products provide options for formulators in the plastics, joint compound, and caulk and sealant industries. Coarser Vical® GCC products are excellent raw materials for glass, vinyl composite floor tile, asphalt shingles and other roofing materials, while Marblemix® GCCs are manufactured especially for swimming pool and spa plastering. 

Like all Specialty Minerals-Performance Minerals plants, Lucerne Valley is certified ISO 9001 and uses rigorous quality monitoring and continuous improvement processes to provide customers with uniform, high-quality products.
