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.
