Galena: Mineral information, data and localities.

Galena Group. Galena is the primary ore mineral of lead. Worked for its lead and silver contents (the latter as minute inclusions of various silver sulphosalts) 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.

Research progress on electrochemical characteristics of galena in

Galena (PbS) is the most important lead-bearing mineral and a major source of lead metal worldwide. As a sulfide mineral, galena often coexists with other valuable sulfides such as chalcopyrite (CuFeS 2) and sphalerite (ZnS), as well as the gangue mineral pyrite (FeS 2) [1].The separation of galena from these other minerals is accomplished through froth flotation [2], …

Galena: The mineral galena information and pictures

Galena is by far the greatest ore of lead. The extraction process to remove the lead from the sulfur is very simple, thus lead has been extracted from Galena since the earliest times. Galena from certain regions is rich in silver, and some specimens may contain as much as 20 percent silver. Because of this, silver-rich Galena is also an ore of silver. . Another use of Galena was its …
