Antimony (Latin: stibium) is a chemical element with symbol Sb and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds have been known since ancient times and were used for cosmetics; metallic antimony was also known, but it was erroneously identified as lead. It was established to be an element around the 17th century.
 

For some time, China has been the largest producer of antimony and its compounds, with most production coming from theXikuangshan Mine in Hunan. The industrial methods to produce antimony are roasting and subsequent carbothermal reduction or direct reduction of stibnite with iron.
 

The largest applications for metallic antimony are as alloying material for lead and tin and for lead antimony plates in lead-acid batteries. Alloying lead and tin with antimony improves the properties of the alloys which are used in solders, bullets andplain bearings. Antimony compounds are prominent additives for chlorine- and bromine-containing fire retardants found in many commercial and domestic products. An emerging application is the use of antimony in microelectronics.
 

Any of the natural mineral formations containing antimony in compounds and concentrations that make commercial use technically and economically feasible. Of the antimony ores proper, the major mineral is antimonite (Sb2S3), which contains up to 71.4 percent Sb; in rare cases, antimony ores are represented by complex sulfides of antimony, copper, mercury, lead, and iron (berthierite, jamesonite, tetrahedrite, livingstonite), as well as by oxides and oxychlorides (senarmon-tite, nadorite) of antimony. The content of Sb ranges from 1 to 10 percent in blanket deposits and from 3 to 50 percent in veins, with the average content varying between 5 and 20 percent. Antimony ores are formed through the filling of rock fissures by low-temperature hydrothermal solutions, as well as through the replacement of the solutions by antimony minerals.


There are two types of antimony deposits of industrial significance. The first type includes bedded bodies, lenses, pockets, and stockworks in consistent sheetlike formations deriving from metasomatic replacement of limestones by silica and antimony compounds under a shale cap rock (Chikuan Shan in China; Kadamdzhai, Tereksai, and Dzhizhikrut in Soviet Middle Asia). The second type of deposit comprises systems of steeply dipping quartz-antimonite crossveins in shales (Turgai, Razdol’noe, and Sarylakh in the USSR; Gravelotte in South Africa). Quartz-antimonite ores are practically monometallic, while the polysulfide complex ores sometimes contain admixtures of fluorite and of minerals of Hg, Au, Ag, Cu, Pb, Zn, W, Sn, and As.
