Galena is a lead sulfide mineral. It is the world's most important ore of lead and a significant ore of silver. ... In addition to silver, galena can contain minor amounts of antimony, arsenic, bismuth, cadmium, copper, and zinc. Sometimes selenium substitutes for sulfur in galena.
Lead is a corrosion-resistant metal with many industrial uses. It is used in ammunition. Zinc also is anti-corrosive and is used in construction material. The earliest period of lead mining in Kansas was probably in Linn County in the 1830's, but the first commercial production of lead in the state was near Galena …
Zinc (Zn) is a bluish-white lustrous metal that is brittle at room temperature, but malleable when heated. It has a low melting point (419.5°C) and a moderately high specific gravity (7.13). Lead (Pb) is a soft, ductile, malleable, bluish-white metal with a low melting point (327.4°C) and a high specific gravity (11.3). Zinc and lead minerals often occur together because, as elements, they ...
Lead ore is most commonly found as lead sulphide (PbS), galena, a heavy, shiny grey metallic ore with a conspicuous cubic cleavage, but locally pyromorphite, lead chlorophosphate (Pb 5 (PO 4) 3 Cl), was worked on Green Hill, near Charterhouse and on Blagdon Hill. Around Charterhouse, the lead ore contained small amounts of silver.
There, lead ore, primarily galena (lead sulphide, PbS), and zinc ore, primarily sphalerite (zinc sulphide, ZnS, also called "jack," blende, or "resin jack"), occur in subsurface rock formations and are dug in shallow or deep mines. The Oklahoma mines tended to be deeper than others of the Tri-State.
Galena also was a major mineral of the zinc-lead mines of the tri-state district around Joplin in southwestern Missouri and the adjoining areas of Kansas and Oklahoma. Galena is also an important ore mineral in the silver mining regions of Colorado, Idaho, Utah and Montana.
Galena Lead Mine Superfund Site, Galena, Kansas . Overview . Property Loss Caused by July 2006 Subsidence Event in Downtown Galena. Site Location . Galena is a city of approximately 3200 people in southeastern Kansas. The city was named after the lead ore, known as galena, found in the area in the latter part of the 19th century.
The problem of treating oxidized lead-zinc ores for the production of high-grade lead zinc flotation concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals. The ore for treatment is a lead-zinc carbonate ore in a mixed siliceous-lime carbonate gangue.
A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue. Forms of Lead and Zinc Ore The two principal minerals containing lead and zinc are galena and ...
Lead ore was the first metal ore mined in Wisconsin, followed by zinc and iron. Although southwestern Wisconsin is best known today for its rich farmlands, place names such as Mineral Point, Hardscrabble, New Diggings, Black Jack and Lead Mine evoke an earlier time when local mines produced much of the nation's lead.
Apr 04, 2016· Galena-sphalerite-quartz (lead-zinc ore) from Mexico. (4.2 cm across at its widest) Silvery-gray = galena (PbS) Mottled brownish-gray = sphalerite (ZnS) Whitish-gray = quartz (SiO2) A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties.
Illinois Mines. BrineyCoal Mine - Terra Cotta, Illinois ... Largescale commercial lead and zinc mining in the Upper Mississippi Valley Lead and Zinc District began in the 1820s and continued until active mining ceased in 1979. ...

Aug 13, 2008· He zinc is absorbed by the ash, and at some point the bead of metal will blick, that is suddenly become very bright. This is now pure silver (around 99.98%, if the galena doesn't bear too many other zinc-soluble impurities) Remember that lead vapour is toxic, and so is the sulphur dioxide liberated in smelting sulphide ores.
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.
Galena, Kansas – A Lead Mining Maven . Galena, Kansas, 1898. In the rocky hills and gravel-filled valleys of southeast Kansas is the small town of Galena, born of rugged characters when lead was discovered in 1877. Before this time, the land was only sparsely settled by hunters and farmers earning meager livings from the rocky and sterile ...
The relative galena and sphalerite contents do not change the surface chemistry and tend only to have an impact in cases where the galena content is higher than the sphalerite content, e.g. at Cannington where if the lead feed grade relative to zinc is too high, then too much of the faster floating zinc with lower iron content is recovered to ...
galena, or lead sulfide (PbS), and zinc was obtained from sphalerite, or zinc sulfide (ZnS). Galena and sphalerite were not useful in their dispersed natural form. The ore-bearing host rock had to be milled, and galena and sphal-erite concentrates had to be sent to smelting plants, which separated the lead and zinc metals from the sulfur-bearing
Lead-Zinc in Southwest Missouri outside the Tri-State District Lead was first mined in Greene, Webster, and Christian counties in the 1850s. Most mining in southwest Missouri from the 1870s to the 1940s was in these three counties plus Taney, Ozark, Wright, Dade, Howell and Texas counties.

History of Lead Mining in Missouri. It is no coincidence that Missouri's official State Mineral is Galena, the major source of lead ore. For most of the late 19th and early 20th Centuries, Missouri was the global leader in lead production, and even today some of the largest and most important remaining lead deposits in the world are located in ...
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.
Empire City was annexed into Galena as its Fifth Ward in 1910. By that time, Galena boasted three banks, three newspapers, and an opera house. Though its primary lead and zinc mining and smelting remained its principal industries, there were also foundries, stamping works, grain elevators, a novelty works, and a broom factory.
