Lead processing Mining and concentrating Britannica

Lead processing Lead processing Mining and concentrating: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills. Here the ore is finely crushed, sometimes to particle diameters of less than 0.1 millimetre (0.004 inch), and then treated by one of several mineral

Extracting Lead Materials from Ore

Extracting Lead Materials from Ore. Lead is a dense, soft, low-melting metal. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays.Lead resists corrosion by water, so it makes a long-lasting roofing material.. Only about half of the lead materials used today are produced from mining, the rest is obtained from

Pre-Columbian lead pollution from Native American galena

Archaeological records indicate that galena (PbS, a lead-sulfide mineral and primary lead ore) was utilized by pre-Columbian Native American populations in eastern North America for nearly 10,000 yr (Walthall, 1981).While some evidence has indicated that pre-Columbian societies generated limited lead (Pb) pollution as a biproduct of copper mining (Pompeani et al., 2013) and biomass burning

The Jack Waite Mine: A Leading Lead Producer in Two States

Oddly, the nature of the ore changed at the state line, and the mine extracted ore out of two vastly different bodies throughout its history. Since it was situated on a state line, the mine had to report two different production statistics, one for each state. At one time, the Jack Waite was the leading lead producer in both Montana and Idaho.
