Stibnite is formed of antimony (Sb) and sulphur (S), and occurs in low-temperature hydrothermal ore deposits, hot spring deposits and volcanic condensates. Antimony is an important metal widely used in military as well as daily civilian applications. Stibnite is an important raw material in extraction of antimony.
