High Quality Building Products Using Specialty Minerals Ground Calcium Carbonates and Talcs

Today’s beautiful homes and attractive commercial and industrial buildings result from the development of high-quality, durable components manufactured by the building products industry.

Limestone, or ground calcium carbonate, is one of the most commonly used minerals in building products and construction applications, along with a related mineral, dolomite, a calcium magnesium carbonate.  As fillers and extenders, these materials provide improved performance and cost benefits to a broad range of industrial, environmental, and agriculture applications that impact our daily lives. Building product applications include asphalt roofing shingles, vinyl floor tile and sheeting, tape joint compounds, glass, stucco, concrete, masonry, and swimming pool and spa plasters. Talcs are also used, generally in joint compounds.

Chemical purity, as well as optical brightness and color, which vary with each deposit, play a major role in the end value for the application. Combining extensive Research and Development with Application Technology and support to customer trials, Specialty Minerals is well positioned to supply you with high-performance  products or to work with you to develop new grades tailored to your building product application.

Specialty Minerals Products for Building Components
Specialty Minerals supplies crushed, screened, ground, and pulverized limestone and dolomite products direct from our quarries in Adams, Massachusetts, Canaan, Connecticut, and Lucerne Valley, California. Talc is mined and ground in Barretts, Montana, and imported talc ore is ground in Mount Vernon.

  • SMI Eastern Limestones – high brightness ground calcium carbonates (GCCs), also called ground limestones, manufactured in sizes ranging from 1” decorative stones down to 3 micron fine industrial grades.  Adams, Massachusetts is the location of the mine and plant.
  • SMI Eastern Dolomites – ground and screened dolomites (calcium magnesium carbonates) from 4 mesh to 325 mesh, from a mine and plant in Canaan, Connecticut.
  • SMI Western Limestones – high and medium brightness ground calcium carbonates, spanning the particle range from 10 mesh coarser grades down to 2 micron industrial grades. This plant is located in Lucerne Valley, California.
  • SMI Talcs for Building Products – white talcs used in joint compounds, manufactured in Barretts, Montana.
