Bismuth ore

Bismuth is a light pink colored, brittle, crystalline and shiny metal. It has various uses such bismuth ore cosmetics, alloys, fire extinguishers and ammunition.

World reserves of bismuth are usually based on bismuth content of lead resources because bismuth production is most often a byproduct of processing lead ores; in China, bismuth production is a byproduct of tungsten and other metal ore processing. Bismuth minerals rarely occur in mines that produced bismuth from a bismuth ore. The Tasna mine in Bolivia, which has the largest deposits of bismuth, and one mine in China are the only mines that have produced bismuth from a bismuth ore. Pure bismuth can also be obtained by reducing the oxide with carbon or by roasting the sulfide in the presence of charcoal and metallic iron to remove the sulfur. World bismuth reserves are estimated at , tonnes.

Bismuth is a chemical element ; it has symbol Bi and atomic number It is a post-transition metal and one of the pnictogens , with chemical properties resembling its lighter group 15 siblings arsenic and antimony. Elemental bismuth occurs naturally, and its sulfide and oxide forms are important commercial ores. It is a brittle metal with a silvery-white color when freshly produced. Surface oxidation generally gives samples of the metal a somewhat rosy cast.

The Ohio State University. Bismuth Bi is a heavy metal with an atomic number of 83 and an atomic mass of Elemental bismuth is nontoxic, but bismuth salts can cause toxicity. Bismuth salts are relatively insoluble, so environmental and occupational exposure is low. Most toxic exposure to bismuth is from consumption, usually from medicinal use. Video 1: How to make bismuth crystals using a bismuth ingot. While not related to bismuth toxicity, this video is an interesting look into some of the properties of bismuth. Bismuth salts are used for a variety of gastrointestinal disorders. Antacids, such as bismuth subnitrate, bismuth subcarbonate, and bismuth subgallate, are used for diarrhea, flatulence, intestinal cramping, constipation, and dyspepsia. Bismuth is also used in surgical packing and pastes used for ileostomies and colostomies.
