stibnite, antimony sulfide (Sb 2 S 3 ), the principal ore of antimony. This mineral has a brilliant metallic lustre, is lead- to steel-gray in colour, and fuses readily in a candle flame (at about 525° C [977° F]). It often possesses a bladed habit, is striated, and has one perfect cleavage. Stibnite occurs in massive forms in gneiss and granite.

First, stibnite showed a gradual enrichment process in both deposits, with a large amount of precipitation in the final stage (stibnite-quartz stage or stibnite stage). The later-stage stibnite at Woxi may have precipitated during the Early Cretaceous, similar to the Banxi stibnite (~130 Ma; Li et al., 2018 ).

Stibnite, or antimony trisulfide (Sb 2 S 3 ), is the most abundant of the roughly 100 antimony-bearing minerals. Antimony's chemical symbol (Sb) stems from stibium, the Latin word for stibnite. The origin of the word "antimony", however, is uncertain. One possibility is the 15th-century Middle English word antimonie, which literally means ...
