Galena ore

Bulk assays of an ore are useful in indicating possible mineral constitution. For example, an ore containing copper, lead, and bismuth may be expected to contain chalcopyrite, galena, and native bismuth, but it may contain also rarer minerals such as galenobismutite (PbBi 2 S 4), wittichenite (CU 3 BiS 3), or aikinite (PbCuBiS 3).

In the peak year of 1845, the mining district, with Galena as its hub, produced almost 85% of the nation’s lead. The “Lead Rush” preceded the California “Gold Rush” by 20 years. Galena claimed 9 residents who reached the rank of General for service rendered during the Civil War. 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. Wisconsin lead mining peaked in the 1840s. In 1844, a third of the region's residents left for copper and iron mines elsewhere and the discovery of gold in California caused many others to head west in 1849.Galena is by far the greatest ore of lead. Galena is the most common mineral containing lead, and contains mostly lead. Since the extraction process is so simple, lead has been extracted from Galena since the earliest times.

This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.As nouns the difference between galena and graphite is that galena is a mineral, lead sulphide (PbS), mined as an ore for lead while graphite is an allotrope of carbon consisting of planes of carbon atoms arranged in hexagonal arrays with the planes stacked loosely that is used as a dry lubricant and in "lead" pencils.
