stibnite

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.

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.

Stibnite and galena have been observed at several occurrences in the field.
