One major reason why transition metals are good catalysts is that they can shuttle between oxidation states. This flexibility lets them slide in and out of chemical bonds; so, for instance, they can snip a bond between carbon and boron and then stitch a carbonfluorine bond in its place. Planas et al. now report that bismuth can also orchestrate such bondswapping events.

Bismuth is alloyed with iron to create what is known as "malleable irons." Bismuth compounds are used in stomachupset medicines (hence the trademarked name PeptoBismol), treatment of stomach ulcers, soothing creams, and cosmetics.

Often we hear that copper concentrates have contaminants which affect the incomes to be obtained by commercialization. Well, one of the worst contaminant is bismuth because is difficult to remove during smelting process and the metallic copper to be obtained at the end of the process will be brittle and consequently its mechanical properties will be very bad. Ergo, the objective is focused to

Bismuth is nearly always found in nature in the metallic state; but occasionally it is met with as sulphide in bismuthine and as carbonate in bismutite. It is also found in some comparatively rare minerals, such as tetradymite, combined with tellurium, and associated with gold. In minute quantities it is widely distributed: it is a common constituent of most copper ores; hence it finds its way
