United States Antimony Corp
United States Antimony Corp. engages in the exploration, production and sale of precious metals. The company is headquartered in Thompson Falls, Montana and currently employs 69 full-time employees. The firm is organized and managed by four segments, which represent its operating units, including the United States antimony operations, Mexican antimony operations, precious metals recovery and United States zeolite operations. Its antimony smelter and precious metals plant is located in the Burns Mining District of Sanders County, Montana. Antimony oxide is a fine, white powder that is used primarily in conjunction with a halogen to form a synergistic flame-retardant system for plastics, rubber, fiberglass, textile goods, paints, coatings and paper. Its antimony oxide is also used as a color fastener in paint, as a catalyst for the production of polyester resins for fibers and film, as a catalyst for the production of polyethylene pthalate in plastic bottles, as a phosphorescent agent in fluorescent light bulbs, and as an opacifier for porcelain.
