2016-10-18Lead mining and smelting began in the New World almost as soon as the first colonists were settled. By 1621 the metal was being mined and forged in Virginia. The low melting temperature of lead made it highly malleable, even at the most primitive forges. Furthermore, leads resistance to corrosion greatly enhanced its strength and durability

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
