Evaluation of a method for arsenic(III) and antimony(III ...
Feb 08, 2016· Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and …

Recovery of Antimony: A Laboratory Study on the Thermal ...
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 antimony is refined.[]

Microbial Methylation of Metalloids: Arsenic, Antimony ...
1. Introduction. At present, most antimony smelters still adopt the volatilization process in blast furnace to extract antimony trioxide (Froehlich et al., 2017), and reduce it by coke in a reverberatory furnace to metallic antimony (Anderson, 2012).This process chain, however, has drawbacks, such as low efficiency, high energy consumption (around 3.6 × 10 7 kJ/t Sb) and high operation ...
