Galena, Kansas – A Lead Mining Maven. Galena, Kansas, 1898. In the rocky hills and gravelfilled 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 soil.
· Turning Abra from a lead mine into a gold mine is what might be called the bluesky appeal of Galena with first sniffs of a gold and copper zone revealed in deep drilling under the leadsilver zone with encouraging grades such as 12m of /t gold from 706m and at /t gold plus % copper from 631m.
· There are two types of lead–zinc ore bodies,, sandstonehosted ores (SHO) and limestonehosted ores (LHO), in the Jinding giant sulfide deposit, Yunnan, SW China. Structural analysis suggests that thrust faults and dome structures are the major structural elements controlling lead–zinc mineralization. The two types of ore bodies are preserved in two thrust sheets in a threelayered ...
Lead isotopic compositions of 12 galenas from five late Archaicinitial Woodland grave and habitation sites in southern Ontario have made it possible to determine the "most likely" source areas for the galenas. For one of the oldest sites (Finlan), the most likely source is in the southwestern Upper Mississippi Valley (WisconsinIllinoisIowa) mineral district.
· While the decline in demand for lead led to its long decline, it is now a very popular place to visit in Illinois due to its wealth of wellpreserved historic houses and beautiful old buildings. Remarkably, the Galena Historic District encompasses over 800 such properties, including the former homes of such famed figures as Ulysses. S Grant and Elihu B Washburne. Other things to do in Galena ...
· Native American use of galena at Kincaid Mounds, a settlement occupied during the Mississippian period (1150 to 1450 CE), resulted in more than metric tons of .
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, silverrich Galena is also an ore of silver. . Another use of Galena was its importance ...
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, tennantitetetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.

· Rock Hunting Galena, a Heavy Metal. Personally, I think Galena would be a great name for a heavy metal band. Of course, that's in a perfect world where more than geologists and rock hounds would get the joke. Galena is a sulfide mineral and the most common mineral ore of lead. There are certainly other types of lead minerals.
Galena Mining (ASX:G1A) owns the Abra base metals project loed in the Gascoyne region of Western Australia — home to one of the largest lead and silver deposits in the world set to produce ...
· Galena is the most important leadcontaining mineral that has semiconductor properties which can cause electrochemical reactions during flotation. This paper reviews studies of galena electrochemical flotation behavior. The electrochemical mechanisms on galena surfaces of oxidation, collector adsorption and depression are described. Collectorless flotation requires a moderate .

· SEDEX ore minerals typically include iron, zinc and lead sulphide minerals. These minerals are precipitated when metalrich hydrothermal fluids come in contact with hydrogen sulphide produced by bacteria in the seawater. The most common ore minerals are iron sulphides (pyrite and pyrrhotite), zinc sulphides (sphalerite) and lead sulphides (galena).
