Lead (Pb) is next in abundance with 120 to 150 lead bearings minerals known. The commonest lead ore is the sulphide galena (PbS). The commonest lead ore is the sulphide galena (PbS). Other forms are known but dont often occur as ore minerals.
The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS. Galena is lead sulfide with a hardness of 2.5 on the Moh's scale actually quite soft but it is VERY heavy with a specific gravity of 7.4 to 7.6.
The large volume of Galena that is processed for lead produces enough Silver as a by product to make Galena the leading ore of Silver. To quote Allen N Wollscheidt, quot;Galena, back 75 years ago, was the stuff the crystal of crystal radio sets.

Chemical Formula PbS Galena is the primary ore mineral of lead. Its discovery dates back to 3000 BC, and its name is derived from the Latin word galena, meaning dross from melted lead.
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 (PbS) is lead sulfide, the principal ore of lead. It is steel gray, heavy (specific gravity is 7.4 to 7.6), and opaque and has a bright metallic silver colored luster, although the shiny surface may be dulled by a coating of lead carbonate.
Did you know 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 their size.
Galena definition, a common, heavy mineral, lead sulfide, PbS, occurring in lead gray crystals, usually cubes, and cleavable masses the principal ore of lead. See more.
Galena is by far the greatest ore of lead. The extract ion 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.
Galena is a see also of lead. As nouns the difference between galena and lead is that galena is (mineral) a mineral, lead sulphide (pbs), mined as an ore for lead while lead is (uncountable) a heavy, pliable, inelastic metal element, having a bright, bluish color, but easily tarnished; both malleable and ductile, though with little tenacity it is easily fusible, forms alloys with other metals
Lead is a heavy, soft, ductile metal with a low melting point. Its chemical symbol is Pb. Its main ore mineral is galena (PbS). The main uses for lead are in
Galena Easily recognized by it good cleavage, high specific gravity, softness, and lead gray streak, this mineral is the primary ore mineral of lead. It is a very common sulfide that has been worked for its lead content as early as 3000 BC.
Named for the Latin word galena which was given to lead ore or the dross from melted lead. Galena is a common mineral and widespread mineral with thousands of localities worldwide. Noted deposits include in the United States, the Czech Republic, Germany, France, England, Scotland, and Mexico.
galena (gl180;n) or lead glance, lustrous, blue gray mineral crystallizing usually in cubes, sometimes in octahedrons. It is the most important ore and the principal source of lead. It consists of lead sulfide, PbS, but frequently contains silver (it is mined for this metal
Cerussite (PbCO 3) and angle site (PbSO 4) commonly occur in the near surface weathered or oxidized zone of a lead ore body. Deposits containing lead form from hot (hydro thermal) fluids generated within the earth which may be trapped below the surface in cracks where galena and other minerals may precipitate to make vein deposits.quot;
Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world's primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and metamorphic rocks in medium to low temperature hydrothermal veins.
Galena PbS c 2001 2005 Mineral Data Publishing, version 1 Crystal Data Cubic. Point Group 4/m 32/m. Most commonly cubic, crystals to a meter on an edge are
a soft, lead gray, very heavy, crystalline mineral, lead sulfide, PbS, with a bright metallic luster, that is the chief ore of lead see also glance 2 Websters New World College Dictionary, 4th Edition.
Oct 28, 20180183;32;(mineralogy) A mineral, lead sulphide (PbS), mined as an ore for lead. [From circa 1600.] 1939 November, Raymond B. Wailes, Chemical Engineering for Home Experimenters, Popular Science, page 207, You can easily extract lead from galena, a natural mineral which has been used in crystal radio receivers. 1942, G. F. Loughlin, A. H. Koschmann
A major and primary Lead mineral is galena (chemical formula = PbS) which comprises of 86.6% of Lead . In order to smelt this mineral, a blast furnace is needed to be used. A blast furnace is an enormous oven which is used to accomplish the smelting processes .
A gray mineral, essentially PbS, the principal ore of lead. [Latin galna, lead ore.] galena A gray, metallic mineral consisting of lead and sulfur. Galena usually occurs in cube shaped crystals within veins of igneous rock or in sedimentary rocks. It is the main ore of lead.
We are Lead Ore Minerals, Lead concentrates minerals, and Galena exporters and sellers. Want to learn how to start Lead Ore minerals export from Nigeria? Here's how. The main lead mineral is Galena (PbS), also known as Lead Glance. Lead (Pb) is one of the oldest metals known to humans.
