Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was erroneously ...
Antimony is also used for pigments in plastics, paints, rubber, and for a wide variety of minor uses, including medicines, fireworks and others. Antimony oxide is a brilliant yellow color, accounting for much of the pigment use. A tiny amount of highly purified antimony metal is used in the computer industry to make semiconductors.
Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.

5.2 x 4.5 x 3.5 cm. A rich, old-time specimen of massive, native antimony ore in matrix from a classic Canadian locale - the Prince William Mine in New Brunswick. Not pretty to look at, but it is very rich ore and highly representative of the species and locale. Native antimony is not that common, worldwide. Ex. Mullane Collection.

Antimony, a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table). Antimony exists in many allotropic forms. It is a lustrous, silvery, bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite.
Antimony is viewed by the U.S. Consumer Product Safety Commission (CPSC) and Environmental Protection Agency (EPA) as a metal compound to be limited by federal regulation. As covered in a recent article, Toxic Chemicals in Children’s Toys , it is one of eight heavy metals limited by the CPSC in the manufacture of products for children 12 ...

Bolivia is historically known for its many mineral and metal resources, with some metals such as silver having been in exploitation since the Spanish conquest in the 16th century. Other relevant ones are gold, zinc, tin, copper, antimony, rare earths, iron ore, lead, lithium, nickel, magnesium potash and tungsten.
One of the first known eye-shadows was the green ore malachite (CuCO 3.Cu(OH) 2) used as long ago as 5000 BC. By 3500 BC, Egyptian women were using a finely ground form of antimony trisulfide (the ore stibnite, Sb 2 S 3 ) to darken their eye-lids and to give lustre to their eyes ( Selinger, 1994 ).
An ore carrier loads up at the Milne Inlet port of the Mary River Mine on north Baffin Island. Denmark, on behalf of its autonomous territory Greenland, has requested a say in the next phase of development of the mine, citing transboundary impacts.
