Stibnite is a compound of antimony (Sb) and sulfur (S), with the formula Sb 2 S 3. Stibnite is a member of the orthorhombic system, often occurring as long, prismatic 4-sided crystals with pyramidal …
From the medieval latin 'antimonium', originally applied to stibnite. The etymology is uncertain; the popular etymology, from ἀντίμοναχός anti-monachos or French antimoine, still has adherents; this would mean "monk-killer", and is explained by many early alchemists being monks, and antimony being poisonous.
Stibnite (Sb 2 S 3), is generally the primary source of antimony in the natural environment, often occurring alongside minerals such as realgar, pyrite, cinnabar, galena, arsenopyrite, hornblende, calcite, ankerite, barite, and chalcedony (Andreae et al., 1981). One significant antimony ore deposit is the Xikuangshan mine, considered the world ...
One of the Museum's newest and most spectacular mineral specimens, a 1,000-pound stibnite with hundreds of sword-like, metallic blue-gray crystals sprouting from a rocky base, will go on display April 4.
Stibnite is distinctive when coarse-grained but fine-grained occurrences can easily be confused with a plethora of lead-antimony (Pb-Sb) sulphosalt minerals: in such cases …
