Lead processing - Mining and concentrating | …
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 ...
Lead Ore - an overview | ScienceDirect Topics
The ratios of the four lead isotopes (Pb 204, Pb 206, Pb 207, and Pb 208) in a lead ore specimen will depend upon the geological age of deposition of the ore. Thus, the lead isotope ratios are used to source the deposit used to produce archaeological objects containing lead.

HISTORICAL PRODUCTION AND USES OF LEAD
Such simple technology is possible for lead, as lead oxide can be reduced in charcoal or stone fires below 800°C, and more importantly, lead can undergo a double decomposition reaction, in which lead ore reacts with ore which has been oxidised at the top of the furnace, to yield lead metal and release sulphur dioxide gas.
