antimony ore reduce
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 antimony is refined.[ 1 ]
