Stibnite [Sb 2 S 3] is the principal antimony sulfide mineral associated with gold, although berthierite [FeSb 2 S 4] and gudmundite [FeSbS] have also been reported (Davies and Paterson, 1986). The chemistry of stibnite in oxygenated alkaline cyanide solutions is very similar to that of orpiment [As 2 S 3 ] and has the effect of consuming both ...

Stibnite is a chief ore of antimony, which is a crucial mineral with industrial and medical uses. It is a sulfate mineral often found in hydrothermal veins. In the initial stages, stibnite is lustrous gray, black, and silver, and when fully formed, it exhibits an iridescent quality that is muchly prized and collected.

Antimony is not very abundant element. It is present in around 0.5 ppm [3]. In nature, it is present in the form of mineral, such as stibnite, which is its sulfide mineral (Sb 2 S 3). Antimony is found in more than 100 types of minerals. In early days, China was the biggest producer of antimony, which supply around 84% of the world share.

Antimony tends to concentrate in sulfide ores along with copper, lead and silver. It occurs sparingly as a free element, but when it does it is usually in association with arsenic, bismuth or silver. The principal ore minerals of antimony are stibnite and jamesonite, but it can also be a byproduct of certain other minerals.
