The main ore mineral of lead is galena, which is a lead sulphide. When pure, galena contains 86% lead. The lead carbonate mineral cerussite and the lead sulphate mineral anglesite are also important lead ore minerals and are found in the oxidised zone of lead deposits. Lead ores may contain other minerals of metals such as those containing ...
