Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting point of 327 176;C (621 176;F), coupled with its easy
Australias total resources of zinc, lead and silver declined by around 5% in 2012. Total identified resources of zinc decreased to 92 Mt in 2012 from 97 Mt in 2011 while lead decreased by 3 Mt in 2012 to 58 Mt and silver decreased by 6 kt to 125 kt.
