About Pb-Cu. Lead and zinc are extremely close in nature, especially in primary deposits, and often coexist. Most of the lead-zinc minerals are sulfides and sulfates, and galena and sphalerite are the primary Pb-Zn ores. Non-sulfide: It is formed due to hypogene and supergene weathering. Mostly oxide ores like zincite, and cerussite may fall under this category.
