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 …
