Discovered bismuth
WebCobalt was discovered by Georg Brandt, a Swedish chemist, in 1739. Brandt was attempting to prove that the ability of certain minerals to color glass blue was due to an unknown element and not to bismuth, as was commonly believed at the time.Cobalt's primary ores are cobaltite (CoAsS) and erythrite (Co 3 (AsO 4) 2).Cobalt is usually … WebBismuth does occur free in nature and in such minerals as bismuthinite (Bi 2 S 3) and bismite (Bi 2 O 3). The largest deposits of bismuth are found in Bolivia, although …
