Rhodium minerals

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.

Bowieite is a rhodium-iridium-platinum sulfide mineral , found in platinum-alloy nuggets from Goodnews Bay, Alaska. It was named (by the IMA in 1984) after the British scientist Stanley Bowie (1917–2008), in recognition of his work on identification of opaque minerals.

Rhodite or rhodian gold is a naturally occurring alloy of gold and rhodium found in gold ore. Gold ore containing 34 to 43% rhodium was reported from Mexico and Colombia in 1825. The alloy displays brittle tendencies and has a density of 15.5 - 16.8 g/cm3.
