Primary tin ore deposits are part of magmatic-hydrothermal systems invariably related to late granite phases (tin granites, pegmatites, tin porphyries), and may become dispersed by exogenic processes and then eventually form placer deposits within a few km from their primary source, due to the density of cassiterite, its hardness and chemical ...

Lead ore is primarily composed of lead sulfide (PbS), which is the most common mineral form of lead. Other minerals that may be present in lead ore deposits include cerussite (lead carbonate, PbCO3), anglesite (lead sulfate, PbSO4), galenite (lead sulfide, PbS), and other lead-bearing minerals. The concentration of lead in lead ore deposits can vary widely, ranging …
