A Review on Pyrometallurgical Extraction of Antimony from …
The process of the stibnite decomposition in an airtight vessel was patented in 1932 for direct production of antimony (but there is no information about its industrial implementation). When stibnite is heated to 1500 °C in absence of oxygen, it will undergo the reactions shown in Equations (21) and (22), producing metallic antimony [ 2 ].

Historically, antimony sulfide carried several Greek and Latin names (anthemon, stibi, stimmi ) until 1430, when Basil Velentine identified the presence of sulfur and renamed it spiessglas. Francois Sulpice Beaudant formally assigned the name stibnite in 1832. The molecular weight of stibnite is dominated by antimony's 71.68% to sulfur's …
