Types of Lead Ores 1) Galena: The Galena is also called Lead Glance. It is an important source of silver and the most important ore of lead. 2) Anglesite: This is a lead sulphate mineral with the chemical formula PbSO4. Anglesite contains 74% of lead by mass and therefore has a high specific gravity of 6.3.

• The majority of the deposits are mixtures of minerals, hence lead ore is usually obtained as a byproduct of other metal mining such as zinc, silver or copper. In fact, lead ore is a main source of silver and contributes substantially towards the world's total output. The most common lead ore is galena (PbS), which contains 86.6% lead.
