Antimony

Introduction. Antimony (Sb, stibium) is a semimetallic element that belongs to the vanadium family (Group VA) of the periodic table and shares certain chemical and physical properties with lead, arsenic, and bismuth [1 ]. In nature, antimony is associated with sulfur as stibnite and occurs in ores with arsenic.

A Review on Pyrometallurgical Extraction of Antimony from …

If considerable antimony sulfide is also present, some iron is added to reduce the sulfide . The main product of the reduction process is a high purity metal, but the slag may also have a high concentration of antimony (5–20% Sb) and requires further treatment for the metal recovery. The antimony yield is between 95 and 98% which …

Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide were analyzed …

Antimony

Antimony is sometimes found as an element, but normally it is found as stibnite, an antimony sulfide mineral. Stibnite is the main ore of antimony. China is the biggest maker of antimony; it makes 84% of all antimony. Other countries that make antimony are South Africa, Bolivia, and Kyrgyzstan. Antimony is not used in the human body.

In the following, we focus in particular on the chemistry of antimony sulfide in selected ILs. The ore stibnite (Sb 2 S 3) is the main source for antimony production. At contents of 40 to 60%, antimony is obtained by reduction with iron at 550 to 600 °C. From ores with lower contents, the sulfide is roasted to Sb 2 O 4 or Sb 2 O 3 and then ...

CHAPTER 2. HEALTH EFFECTS

Pentavalent organic antimony compounds have been used for the last 60 years. The two predominant forms are sodium antimony gluconate (sodium stibogluconate) and meglumine antimoniate (N-methyl-D-glucamine or Glucantime) (Haldar et al. 2011). In the treatment of parasitic diseases, the patient receives multiple injections of the antimony compounds.

The exposure to and health effects of antimony

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.[]
