  • 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.

  • Historical and Global Implications Bismuth

    The US produces Bismuth as a byproduct of its smelting of copper and lead. Bolivia is the largest producer of Bismuth through mining. Peru, Japan, Mexico, and Canada produce Bismuth through mining on a much smaller scale than Bolivia. Still, the overwhelming majority of the Bismuth produced worldwide is as a byproduct of other elements.

  • Bismuth Statistics and Information USGS

    Bismuth is mainly a byproduct of lead ore processing. It has a metallic luster and is silver-white with an iridescent tarnish. Among the heavy metals, it is the heaviest and the only non-toxic. Bismuth has been used in solders, a variety of other alloys, metallurgical additives, and medications and in atomic research.

  • Bismuth an overview ScienceDirect Topics

    Bismuth (Bi) exists in the +3 oxidation state in sea water, probably as the reactive cationic oxyhydroxide species, BiO + and Bi(OH) 2 +, with a minor contribution from Bi(OH) 3.Dissolved bismuth ranges from 25 to 450 fmol kg −1, with the lowest concentrations in the deep North Pacific and the highest at mid-depth (600 m).Vertical profiles of bismuth are complex, as shown in Figure 9.

  • Bismuth Element information, properties and uses

    Bismuth was discovered by an unknown alchemist around 1400 AD. Later that century it was alloyed with lead to make cast type for printers and decorated caskets were being crafted in the metal. Bismuth was often confused with lead; it was likewise a heavy metal and melted at a relatively low temperature making it easy to work.

  • Other Metals Globe Metal Recycling

    In fact, as one of the most effectively recycled materials in the world, more lead is actually produced via recycling rather than through mining. It’s easy and reusable over and over again. For example, with lead batteries, lead ingots recycled from battery grids, other battery parts (e.g. posts and terminals), and lead-oxide are used to
