Specialty Minerals' mine and plant in Lucerne Valley, California, located in the high desert in the southeastern part of the state, has been producing finely ground industrial ground calcium carbonates (GCCs) since 1961. Mining and processing has gone on much longer, since 1848, manufacturing coarser ground limestones for whitewash, agriculture and other lower performance applications. Limestone ore from the adjacent Specialty Minerals quarry is processed into screened and ground calcium carbonates. They are packaged for shipment throughout North America, in bulk truck and bulk rail, 50-pound bags, and semi-bulk bags.
High brightness and purity limestone ores are selected to match the needs of its many users. The ground calcium carbonate is a functional additive and filler for use in a number of industrial markets: building products, plastics, coatings, rubber, caulk and sealants, glass, and gel coats.
Lucerne Valley Ground Calcium Carbonates
Lucerne Valley’s fine ground, bright white Vicron® GCC family of 2 to 13 micron products and Marblewhite® GCC family of 16 to 325 mesh products provide options for formulators in the plastics, paint and coatings, rubber, caulk and sealants industries. Coated fine grind products, Hi-Pflex® and Super-Fil® GCC are ideal for plastics formulations that require high dispersion and low oil absorption. Coarser Vical® GCC products are excellent raw materials for glass, floor tile and roofing manufacturing, while the Marblemix® GCCs are manufactured specifically for pool plastering. Bunker-White® limestone, a unique material, is used to replace sand in bunkers on the golf courses.
