Antimony

Sulfides of copper, zinc, iron, and bismuth may be locally associated with the antimony ores. Antimony was mined intermittently in Arkansas after its discovery in 1873. Mining activity peaked during World War I when metal prices were high. Some ore was recovered from shallow trenches excavated along the trend of the larger veins.

Antimony - Wikipedia

Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.
