Galena Mineral | Uses and Properties
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 tarnish after exposure to air.Galena - Wikipedia,One of the oldest uses of galena was in the eye cosmetic kohl. In Ancient Egypt, this was applied around the eyes to reduce the glare of the desert sun and to repel flies, which were a potential source of disease.

It is the most important ore of Lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic cyrstal system often showing octahedral forms. Galena is the main ore of lead, used since ancient times. Because of its somewhat,Lead ore and mines | Minerals and mines | Foundations of,,Primary lead veins. The primary lead ore was found in thin veins cutting through the rock. In these veins, the galena occurs as either thin layers encrusting on the walls of the vein, or as thin bands, pockets or crystals within the vein. The veins were always associated with other waste minerals known as ‘gangue’, usually calcite (CaCO 3) or barytes (BaSO 4). Many of these veins were very,

Its name is the Latin,Lead - Essential Chemical Industry,Annual production (Primary lead), The most important lead ore is galena (PbS). Other important ores, such as cerrusite (PbCO 3) and anglesite (PbSO 4), may be regarded as weathered products of galena and are usually found nearer the surface. The primary manufacture of lead involves three stages: a) ore concentration b) smelting c) refining (a) Ore concentration. Lead and zinc ores (usually,Lead processing | Britannica,Of the more than 60 known lead-containing minerals, by far the most important primary ore of the metal is the lead sulfide galena (PbS). Galena often contains silver, zinc, copper, cadmium, bismuth, arsenic, and antimony; in fact, the value of the silver content often exceeds that of the lead, in which case it is deemed a silver ore.
