widely used antimony compound is antimony trioxide, used as a flame retardant. It is also found in batteries, pigments, and ceramics/glass. In 1984, 64.5 million lbs. antimony ore was mined and refined. Production of the most commonly used antimony compound, the trioxide, increased during the 1980s to about 31 million lbs, reported in 1985.

Antimony and its compounds were known to the ancients and there is a 5,000-year old antimony vase in the Louvre in Paris. Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. The black form of this pigment, which occurs naturally as the mineral stibnite, was used as mascara and known as khol.The most …

Little or no antimony is mined in the United States. Antimony ore and impure metals are brought into this country from other countries for processing. Small amounts of antimony are also released into the environment by incinerators and coal-burning power plants. The antimony that comes out of the smoke stacks of these plants is attached to very

Antimony's average concentration in the Earth's crust is 0.20 gram per metric ton (g/t). Antimony metal melts at 630.6 oC, has a specific gravity that ranges from 6.62 to 6.69 depending on the method of preparation of the metal, and a hardness of 3 to 3.5 on the Mohs scale and about 55 on the Brinell scale.
