The most abundant antimony mineral in the earth crust is stibnite
(Sb2S3) which is converted to various oxide minerals on weathering.
Most of these, though, are locally procured -- there's a scolicite on stibnite
sourced from a baoli in Nashik and an aquamarine from the dense forest of Karur, Tamil Nadu.
Subsequent microprobe analysis of these minerals has revealed the presence of antimony sulphide (stibnite
Sb2S3) and small quantities of rare native arsenic.
En este trabajo, la bioestratigrafia de los quironomidos fosiles a lo largo de un testigo de 17.000 anos extraido en la laguna Stibnite

The most frequent species of zeolites are stibnite
, chabasite, laumontite, mesolite/mordenite, thomsonite, and analcim.
The August 2001 agreement in principle included the Coeur d'Alene Basin area in litigation, the Grouse Creek mine, the Bunker Hill superfund site and the Stibnite
mine site in central Idaho.
Gold-bearing refractory stibnite
, for example, is pyrometallurgically treated to recover antimony in a process that involves the generation of toxic gases.
The Krinj stibnite
and Awirath Gol boulangerite ocurrences, both in Chitral, are good examples of mineralization along thrust planes.
and galena have been observed at several occurrences in the field.
Midas Gold's Stibnite
gold project in Idaho offers the company a strong investment opportunity with low geopolitical risk, potential for production of more than 300,000 ounces per year (oz/y) of gold, and exploration upside, said Barrick President Kelvin Dushnisky.
More abundant minerals included scheelite (CaW[O.sub.4]) (Figure 6(h)), barite (BaS[O.sub.4]) (Figure 6(g)), rutile (Ti[O.sub.2]) (Figures 6(f) and 6(g)), cotunnite (Pb[Cl.sub.2]) (Figure 7(h)), cinnabar (HgS) (Figure 7(d)), and stibnite
