The most important ores of bismuth are bismuthinite and bismite.
Recycling bismuth is difficult in many of its end uses, primarily because of scattering.
As with lead, overexposure to bismuth can result in the formation of a black deposit on the gingiva, known as a bismuth line.
Bursaite commonly occurs alongside other sulfosalts, such as sphalerite, pyrite, chalcopyrite, bismuth and scheelite.
Radon decays to lead-210, then to bismuth-210, polonium-210 and stabilizes with lead-206.
In modern medicine, bismuth subcarbonate has been made into nanotube arrays that exhibit antibacterial properties.
Bismuth, a pentavalent post-transition metal, chemically resembles arsenic and antimony.
