Lead is obtained from its ores by a method used with many metals. First, the ore is roasted (heated in air). Roasting, also called smelting, converts the ore to a compound of lead and oxygen, lead oxide (PbO 2 ). Lead oxide is then heated with charcoal (pure carbon). The carbon takes oxygen away from the lead
