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.

BEAVER BROOK ANTIMONY MINE REVISITED: AN UPDATE ON

Antimony (Sb) is a non-precious but globally ‘strategic’ metal (BGS, 2015; Mudd et al., 2017), whose most common ore mineral is stibnite (Sb 2 S 3). Antimony is widely used in flame-retardants, but is also used in alloys with other metals, lead-acid batteries, low-friction metals, and cable sheathing. Antimony compounds are also commonly

Antimony ScienceDirect

01/01/2015· Historical Background. Although antimony was not described in detail as an element until the seventeenth century, Antimony mining and smelter processes found around large deposits of antimony in the provinces of Guangxi, Hunan, Yunnan, and Guizhou, China, have resulted in significant contamination of local environments. Data from analysis of soil, sediment, and water samples showed

Antimony: will China continue to control supply?

14/11/2018· 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. “China’s Green Shied strategy should continue to restrict antimony processing and mine supply as its government continues to clean up the environmental damage done in recent years,” says Meyer. However, for the overall market, Russian

Antimony was recognized in compounds by the ancients and was known as a metal at the beginning of the 17th century and possibly much earlier. Its most important mineral is stibnite, a mineral which formed the basis of black eye makeup in Biblical times. Antimony was sometimes confused with lead in those times. It seems not to be clear who first recognised antimony as an element but the French

Antimony Wikipedia

Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was

damnonia.blue: The archaeology of antimony

18/05/2018· Technological background The mining and ore preparation methods employed in working antimony ores were little different to those used in the other hard rock non-ferrous metal mining sectors. Stibnite, the antimony sulphide, had a specific gravity well below that of galena, the lead sulphide, with which it was commonly found in mixed ore deposits and could therefore be easily separate by

Antimony as a health hazard World Problems & Global

Background: Antimony is stable at room temperature but, when heated, burns brilliantly giving off dense white fumes of antimony oxide. It is closely related, chemically, to arsenic. It readily forms alloys with arsenic, lead, tin, zinc, iron and bismuth. High-purity antimony is employed in manufacture of semi-conductors. Normal purity antimony is used widely in the production of alloys to
