Galena - Sphalerite Flotation & Separation Method

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. The association of the minerals and gangue requires a 65 mesh ...

Lead pollution from Native Americans attributed to crushing galena for ...

The sediment isotopes indicated the lead was not native to the Kincaid Mounds site, but instead came from galena deposits located in southeastern and central Missouri as well as the Upper Mississippi Valley. Galena, a lead sulfide mineral that is silvery and sparkles, was abundant in these regions and widely traded across the eastern U.S.
