Lead beads, dating to more than 6,000 years ago, have been found in Turkey, suggesting that galena was known at that time since naturally-occurring metallic lead is rare. To produce lead, galena is ground up and roasted, producing lead oxide, which is heated with carbon in a blast furnace, to make metallic lead.Web

Galena: Mineral information, data and localities.
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. The crystals are bright when fresh but often ...Web

FLOTATION BEHAVIOR OF GALENA AND LEAD …
Lead activation of sphalerite takes place according to the following reaction: ^ ZnS(solid) Pb + + = ^ PbS(solid) Zn+ + ' and the corresponding equilibrium expression is (7) K = (Zn++)/(Pb++) = 103. When the ratio of zinc to lead ions is equal to or greater than the equilibrium constant K, activation does not take place. TheWeb

Galena: Meanings, Properties and Powers
It comes from the Greek word 'galene', meaning lead ore. Since 3000 BC, Galena has been mined for its silver and lead content. Ancient Egyptians used it as kohl under their eyes to reduce the sun's glare and to protect them from diseases carried by flies. Galena is commonly located in Peru, Germany, United Kingdom, Brazil, and the USA.Web

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 …Web
