Higher-than-normal concentrations of antimony have also been detected at certain sites, particularly where antimony is processed for industrial use (e.g., factories) and around sites where hazardous waste is dumped. Although it doesn't accumulate in the human body, antimony can be absorbed and accumulate in plants.

Abstract. To avoid the adverse effects of antimony on the cyanide leaching process used for the recovery of gold from refractory gold ore, a cleaner production process was proposed that would selectively remove antimony as sodium pyroantimonate. The process included three steps: 1) leaching of antimony from the refractory gold ore with sodium ...

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.
