Bismuthinite
(重定向自Bismuth trisulfide)


Bismuthinite is a mineral consisting of bismuth sulfide (Bi2S3). It is an important ore for bismuth. The crystals are steel-grey to off-white with a metallic luster. It is soft enough to be scratched with a fingernail and rather dense.
Bismuthinite forms a series with the lead, copper, bismuth mineral aikinite (PbCuBiS3).
