22 . ANTIMONY (Data in metric tons of antimony content unless otherwise noted) Domestic Production and Use: In 2017, no marketable antimony was mined in the United States. A mine in Nevada that had extracted about 800 tons of stibnite ore from 2013 through .
Antimony crystal, 2 grams, 1 cm. ... It is often found in the company of sulfur, which it bonds tightly, and the most common source for antimony is the sulfurous mineral, stibnite (Sb 2 S 3).
Most antimony is mined as the sulfide; lower grade ores are concentrated by froth flotation, while higher grade ores are heated to 500–600°C, the temperature at which stibnite melts and is separated from the gangue minerals. Antimony can be isolated from the crude antimony sulfide by a .
From the medieval latin 'antimonium', originally applied to stibnite. The etymology is uncertain; the popular etymology, from ἀντίμοναχός antimonachos or French antimoine, still has adherents; this would mean "monkkiller", and is explained by many early alchemists being monks, and antimony .
Antimony is a silverywhite brittle solid found in the earth's crust, estimates of the amount of antimony in the crust are between and ppm. Although antimony resembles a metal it has poor electircal and conductive properties and does not react chemically like a metal and is classified as semimetallic.
Jun 06, 2009· Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. [4] The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.
IMPORTANT NOTE: Stibnite is antimony sulfide and should be handled with care to avoid poisoning, and washing after handling is recommended. One should not ingest antimony, handle or breathe antimony in dust form, or use it in normal elixir form. When cared for and handled properly, there is no danger of poisoning.

It is sometimes found free in nature, but is usually obtained from the ores stibnite (Sb 2 S 3) and valentinite (Sb 2 O 3). Nicolas Lémery, a French chemist, was the first person to scientifically study antimony and its compounds.

Stibnite is the most important ore of the element antimony, and is an industrially important mineral. It was used as a metallic cosmetic in ancient civilization. Stibnite also forms some of the most exceptional crystal formations of all minerals, and large and well crystallized are highly sought after and appreciated by mineral collectors.
Antimony is believed to be found in the Earth's crust at about to parts per million. It is found in over 100 different minerals. Antimony is occasionally found in its pure form, but is most commonly found in the mineral stibnite.
