Markets

Over the years, Franklin has become the leading supplier of some of our nation's most widely used resources.

As the largest and most efficient producer of high-purity chemical grade calcium carbonate and other mineral products such as alumina trihydrate we serve a wide variety industrial and agricultural markets including:

Coatings Adhesives and Sealants Glass and Fiberglass Fertilizer Filler & Agricultural Lime Animal Feed

Plastics and Rubber Fire Retardants Construction Aggregates Floor and Wall Covering

Environmental Application Water & Wastewater Treatment Fluidized Bed Combustion Chemical Processing

Industrial Fillers

*ANIMAL FEED*
		Franklin calcium carbonate is the most widely used source of calcium for animal feed in the United States. We mine from our extensive reserves of the purest limestone with calcium carbonate levels in excess of 97 percent and proven solubility. Then, applying our advanced testing and blending procedures, we tailor feed calcium of the highest quality to the application at hand and the size and dietary requirements of the animal.

*GLASS AND FIBERGLASS*
		Calcium carbonate from Franklin is the most extensively used limestone in the US for producing glass and fiberglass. It is preferred by these manufacturers for its chemical purity and particle size consistency. Franklin is North America's largest supplier of limestone to the glass and fiberglass industries.

*INDUSTRIAL FILLERS*
		Floor and Wall Covering: Carpet, and Ceramic and Vinyl Tile are industrial filer markets where Franklin's versatility in producing custom gradations becomes a critical component in a successful customer/supplier relationship.
		Roofing Materials: Roofing manufacturers represent a market with demanding volume requirements and the potential for significant changes in demand on short notice. Franklin's customer commitment and supply guarantees through multi-plant support have acheived preferred supplier status.
Other: Welding rods, driveway sealants, and industrial caulking products each require different, yet consistent products. Franklin services each of these industries and more.
*CHEMICAL PROCESSING*
Manufacturing Processes: Many chemical manufacturing processes incorporate calcium carbonate in the manufacturing process. In these instances low insoluble residue, high available calcium, and technically competent support are critical to successful ongoing supplier partnerships. Franklin has achieved preferred supplier status at several customer locations. In many instances Franklin has been brought in for support and assistance during customer efforts in product development.

*ENVIRONMENTAL APPLICATIONS*
		Fluidized Bed Combustion: The consistent quality and particle size distribution of Franklin's products, combined with the high absorbancy of our limestones makes these materials preferred reagent products for fluidized bed combustion. Calcium carbonate from Franklin is currently used in both industrial and utility FBC units.
		Water and Wastewater Treatment: The high calcium levels present in Franklin's limestone materials and their excellent solubility have led to the acceptance of Franklin's chemical grade limestone for water and wastewater treatment at several locations.
