Most of antimony produced from antimony-bearing ores is used as flame retardants, catalysts in plastics production, pigments in paints or in production of glassware (Oorts and Smolders, 2009). China is the largest producer of antimony in the world (Yang, 2009). The most important antimony resource exploited in China is the antimony ore

The use of antimony continued in the Iron Age. The Urartian cemetery in Yoncatepe Kalesi in Van (Turkey) yielded antimony buttons made from sulphur-bearing antimony ore, such as stibnite [76: p.188, fig. 9]. Similar antimony and antimony–lead alloy buttons were documented as burial goods from Middle and Late Iron Age Armenia

The ore bodies mainly occur in lamellar, quasi-lamellar and lenticular forms in the altered rocks, and are strictly controlled by anticline structure. In terms of space, elemental paragenesis-separation takes place between gold and antimony deposits, i.e. the gold deposit has antimony ore spots, and the antimony deposit has gold ore spots.

In the United States, antimony(III) trioxide (Sb 2 O 3) is the most commercially significant form of processed antimony.In nature, Sb 2 O 3 exists in minerals such as valentinite and senarmontite (ATSDR 2017; Roper et al. 2012).Antimony is found in nature in these and other mineral species, often in association with arsenic compounds due to their similar geochemical properties.
