Bismuth-Production, Properties, and Applications

In recent times, bismuth ore has been mined only in Bolivia, where bismuth production was restarted in 1989. In the rest of the Western world, bismuth is produced as a by-product from the treatment of copper and lead ores. The practice appears to be similar in the former Soviet Union, where bismuth is also recovered from lead-refining resi­ dues.
