Rhodplumsite is a rare rhodium-lead sulfide mineral, chemical formula Rh3Pb2S2. It was originally discovered within a platinum nugget, in grains up to 40 μm in size. Its name originates from its composition; rhodium and lead (plumbum in Latin). Although this mineral contains large amounts of rhodium, it is not an economically viable ore of rhodium due to its rarity.
