Antimony: The mineral native Antimony information and pictures

Antimony is a minor ore of the element antimony, although most antimony comes from antimony compounds (namely Stibnite), which are much greater in abundance. Antimony has a very interesting property: It is similar to water, in that instead of contracting

Antimony Mining - Encyclopedia of Arkansas

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 ...

Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then either changed to antimony metal or combined with oxygen to form antimony oxide. (1) Antimony trioxide is a white powder that is very slightly soluble in water. (1) Antimony metal is a very brittle, moderately hard metal. (1)

Antimony isotopic composition in river waters affected by ...

Nov 01, 2015  Antimony isotopic composition (δ 123 Sb) of the mine-affected streams ranged from −0.06 to +0.83‰ . It is noteworthy that the most Sb-rich creeks T1 and O1 that both drain former Sb mines (Felgerette and Bournac mine respectively, Fig. 1 ) in the Gardon and Orb watersheds revealed the highest and lowest δ 123 Sb values measured in this ...

Antimony - Earth Resources

When used as an alloying element, antimony greatly increases the hardness and mechanical strength of lead. The main use of antimony is to harden lead in storage batteries, and it is increasingly being used in the semiconductor industry. Historically and economically, antimony is the second most important metallic commodity in Victoria, after gold.

Antimony Minerals Education Coalition

Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.
