Here is a brief summary of the isolation of bismuth.
It is not normally necessary to make bismuth in the laboratory as it is available commercially. Bismuth is found in nature largely as bismite (Bi2O3), bismuthinite (Bi2S3), and bismutite [(BiO)2CO3]. However it is generally made as a byproduct of copper, lead,tin, silver, gold, and zinc plants. The final step involves a reduction of the oxide by charcoal.
