Bi2S3
Bismuth SulfideBismuthinite is an important ore of bismuth. Sprays of steel gray prismatic bismuthinite crystals radiate outward from a common attachment point in the more spectacular specimens of this somewhat rare sulfide mineral. These specimens can not help but be compared to specimens of stibnite. It is difficult to distinguish from the similar looking and closely related antimony sulfide. Bismuthinite is heavier than stibnite and on closer inspection of the crystals, there exists a noticeable difference with bismuthinite’s having straighter, flatter faces. In massive form the confusion is even more pronounced, but bismuthinite is not associated with the typical antimony or arsenic minerals to which stibnite is so commonly allied.

Galena: PbS
Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.
