Galena, also called lead glance, a gray lead sulfide (PbS), the chief ore mineral of lead.One of the most widely distributed sulfide minerals, it occurs in many different types of deposits, often in metalliferous veins, as at Broken Hill, Australia; Coeur d'Alene, Idaho, U.S.; Clausthal Zellerfeld, Ger.; and Cornwall, Eng. Large deposits also occur as …
Galena is the most abundant lead mineral, has been mined for millennia, and remains our major source of that metal. It is a metallic, lead-gray mineral with cubic cleavage and a distinctly high density that makes galena samples feel much 'heavier' than expected for …
2017/12/18· La galena posee generalmente una forma de cristal, que le otorga un aspecto cúbico, pero también puede hallarse como un poliedro de 8 caras (octaedros) e incluso adheridas unas de las otras. Cuando sufre una alteración y le son agregados compuestos de sulfato, este mineral se transforma en anglesita, pero cuando se le …

Galena Group. 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.

Galena is the most common mineral containing lead, and has been well-known throughout the centuries. It is often well crystallized and forms in many interesting and distinct crystal shapes. Some cubic crystals have their edges cut by the partial octahedral growth, some octahedral crystals have their points flattened by cubic growth, and …
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver.[4] Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with ...
