Antimony (Sb) is a toxic metalloid, and its pollution has become a global environmental problem as a result of its extensive use and corresponding Sb-mining activities. The toxicity and mobility of Sb strongly depend on its chemical speciation. In this review, we summarize the current knowledge on t …

Antimony (Sb) is a hard, brittle, silver-white metal with a relatively high specific gravity (6.69) and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point, and decreases contraction during solidification. The metal's main use is to impart stiffness and hardness to lead alloys. …

Antimony is a silverly, lustrous grey metal that exhibits poor heat and electrical conductivity. It is relatively soft, measuring only 3.25 on Moh's scale of mineral hardness. Known as "stibium" in classical Latin, antimony is represented by the chemical symbol Sb. A member of the arsenic group of elements, antimony is commonly found in ...

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.[]

stibnite, antimony sulfide (Sb 2 S 3 ), the principal ore of antimony. This mineral has a brilliant metallic lustre, is lead- to steel-gray in colour, and fuses readily in a candle flame (at about 525° C [977° F]). It often possesses a bladed habit, is striated, and has one perfect cleavage. Stibnite occurs in massive forms in gneiss and granite.

Based on a long-term antimony price of $8,500 a ton, the company estimates that the net present value of the project is around $279m. Future outlook. Although mining antimony is cheaper in China because of labour costs and the typically large deposits, the trend in declining production is set to endure.

The Xikuangshan antimony mine is the world's largest. Since antimony mining began there more than 200 years ago, mine production has increased steadily to the present day. Today, Xikuangshan produces 60 …

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 …
