COPPER - LEAD
Source of byproduct metals



  • Copper -   Reddish metal, malleable and ductile, with high electrical and thermal conductivities. Resistant to air and water but slowly weathers to green patina of basic carbonates. (Historically important alloy, bronze.) Used as wire for conducting electricity; coins; alloys, etc.


  • Lead -   Is a chemical element in the periodic table that has the symbol Pb (Latin: plumbum) and atomic number 82. A soft, heavy, toxic and malleable poor metal, lead is bluish white when freshly cut but tarnishes to dull gray when exposed to air. Lead is used in building construction, lead-acid batteries, bullets and shot, and is part of solder, pewter, and fusible alloys. Lead has the highest atomic number of all stable elements - although the next element, bismuth, has a half life so long it can be considered stable. Like mercury, another heavy metal, lead is a potent neurotoxin which accumulates in soft tissues and bone over time.
