INTRODUCTION. Antimony (Sb) (atomic number 51; atomic mass 121.75 g/mol; density 6.684 g/cm 3; melting point 631°C) occurs naturally as a sulphide ore, stibnite (Sb 2 S 3) and valentinite (Sb 2 0 3).The traditional method of treating the ore is to roast it with charcoal or coke and collect the volatile oxide fume (Sb 4 O 6) from which pure …Web

Antimony is the 63rd-most abundant element in Earth's crust. It is less abundant than tin, arsenic and the rare earths, but more so than bismuth, mercury and silver. Antimony tends to concentrate in sulfide ores along with copper, lead and silver. It occurs sparingly as a free element, but when it does it is usually in association with ...Web

Antimony ore concentrate (principally trisulfide, also called stibnite in less amounts, as well as oxides such as valentinite, senarmontite, and cervantite) was examined in one inhalation study, as was antimony trichloride . Exposed animals were mice, rats, and voles. Exposure doses varied widely and exposure duration ranged from single gift ...Web
