Galena is the primary ore mineral of lead and and ore of Silver. Worked for its lead content as early as 3000 BC. Found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite and skarns. Also found in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces. The crystals are bright when fresh but often tarnish when people touch them. Lead sulfide may contain impurities, such as silver, arsenic, antimony, and copper.
