United States Antimony 

United States Antimony Corporation (UAMY) specializes in the extraction and distribution of antimony, silver, gold, and zeolite products, serving markets across the United States and Canada. Its Antimony division primarily offers antimony oxide, a crucial component that, when combined with halogens, forms a synergistic flame retardant system. This system is vital for enhancing fire resistance in a wide array of materials, including plastics, rubber, fiberglass, textiles, paints, coatings, and paper. Beyond flame retardation, antimony oxide finds additional applications as a color fastener in paints, a catalyst in the production of polyester resins for fibers and films, and in the manufacturing of polyethylene terephthalate (PET) for plastic bottles. It also functions as a phosphorescent agent in fluorescent light bulbs and an opacifying agent in porcelains. The division further supplies sodium antimonite, antimony metal (essential for components such as bearings, storage batteries, and ordnance), and various precious metals. The company's Zeolite division focuses on providing zeolite deposits, which are utilized for a diverse set of purposes. These include agricultural applications like soil amendment and fertilizer, environmental management such as water filtration, sewage treatment, nuclear waste and general environmental cleanup, and odor control. Zeolites are also employed in gas separation and animal nutrition. The versatility of zeolite products extends to their use in catalysts, petroleum refining, concrete mixtures, solar energy and heat exchange systems, desiccants, pellet binding, animal litters (for horses and cats), and floor cleaners. Moreover, they serve as effective carriers for insecticides, pesticides, and herbicides. Established in 1968, United States Antimony Corporation maintains its headquarters in Thompson Falls, Montana.
