Feb 24, 2011. #4. The only galena ore I have ever seen was a solid piece of metal. Since it is lead I would assume it should be easy to find, if you have the right detector. My XLT would find it in a heartbeat (if it reacted the same a lead sinkers) I am not familier woth your machine.
With the decline of the lead mining industry and the start of the California Gold Rush, the population of Galena began to decline and now stands at approximately 3,600 .

By 1845, Galena was producing nearly 27,000 tons of lead ore and Jo Daviess County was producing 80 percent of the lead in the United States. Illinois and Wisconsin lead mining peaked in the 1840s, and a substantial percent of the mining population was lured away by the excitement of the "Gold Rush" in California.

Silver sulfides are the most easily found ores, and those are typically mixed up with the lead sulfide galena (PbS) or with lead carbonate called cerrusite (PbCO 3).The neolithic Anatolian towns knew galena because the people who lived there (in Çatal Höyük, to be exact) about 9000 years ago had made beads out of galena.They wouldn't have noticed …
Recovery of Silver, Gold, and Lead From a Complex Sulfide Ore Using Ferric Chloride, Thiourea, and Brine Leach Solutions By R. G. Sandberg and J. L. Huiatt ... erite, galena, etc.). Gold and silver extraction is usually low and cyanide consumption is high because of base metal complex formation. Several researchers
The discovery of gold in California caused others to head west in 1849. Some that remained began to mine for zinc. ...

Galena, the official state mineral of Wisconsin, is the raw material used to produce lead. During the Wisconsin "lead rush" of the 1820s-40s, lead was more valuable than gold.That is because just about everybody, rich or poor, used objects made of lead in their daily lives – products that ranged from plumbing to toothpaste!
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.
Johnson was not Illinois's first lead miner. The metal was taken, under dubious legal circumstances, as early as 1810. The Vinegar Hill Mine in Galena opened …
Here are some of the chemical, physical, and optical properties of galena: Chemical Properties: Chemical Formula: PbS (Lead Sulfide) Molecular Weight: 239.27 g/mol. Crystal System: Cubic. Hardness: 2.5 on the Mohs scale, which means it is relatively soft and can be easily scratched.
Recovery of Gold from Lead Concentrates. The association of silver with lead minerals, in particular galena [PbS], is well known and documented, but gold is also frequently found in lead concentrates, and its recovery follows closely that of silver. 5.1. Smelting processes. Galena concentrates are usually smelted to produce lead bullion.
lead. materials processing. lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury).

Galena, 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,
In 1876 among the rocky hills and gravel-filled valleys of southeast Kansas, a chance discovery was made that gave birth to Galena – the oldest mining town in Kansas. Named after the natural mineral form of the lead ore discovered, Galena quickly sprang to life and by the turn of the 20th century boasted a population of nearly 30,000.
