A little known fact about lead is that it plays a critical role in smelter operations. Without lead it would be nearly impossible to recover many of the more valuable metals in metallic ores.
Lead is one of the family of elements called heavy metals. It is used in building construction, manufacture of lead-acid batteries, bullets, shot, weights, solders, pewters, fusible alloys, and radiation shielding. It has the highest atomic number (82) of all the stable elements.

Lead is a natural part of many metallic ores, often found in combination with zinc and copper. Colorado has produced billions of pounds of lead during its long mining history.
