Bismuth - Wikipedia

Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a pentavalent post-transition metal and one of the pnictogens with chemical properties resembling its lighter group 15 siblings arsenic and antimony.Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86% as dense as lead.

Mineral resource of the month: bismuth - USGS

Bismuth compounds are most known for their soothing effects on the stomach, wounds and sores. These properties make the compounds an essential part of many medicinal and cosmetic preparations, which until 1930 accounted for about 90 percent of the bismuth used. The subsequent development of low-melting alloys and chemical catalysts containing bismuth, as well as its use as an additive to

Bismuth — Wikipédia

Le bismuth est l'élément chimique de numéro atomique 83, de symbole Bi. C'est le cinquième et dernier élément du groupe des pnictogènes (groupe n o 15). Il est toxique mais moins que le plomb qu'il tend donc à remplacer pour certains usages, et ce n'est pas un oligo-élément : il n'a aucun rôle physiologique connu. Réputé très faiblement présent dans les organismes animaux, sa

Bismuth resources, reserves and production

Bismuth minerals rarely occur in mines that produced bismuth from a bismuth ore. (source: USGS) The most common bismuth minerals are bismuthinite(Bi2S3) and bismite(α-Bi2O3), which are found in minute quantities within other metals' ores. The Tasna mine in Bolivia, which has the largest deposits of bismuth, and one mine in China are the only
