6 天之前 Storia. Il nome della cassiterite deriva dal nome greco dello stagno, Κασσίτερος (kassíteros), ed è stato introdotto dal mineralogista francese François Sulpice Beudant nel 1832; il minerale era tuttavia già noto più di 5000 anni fa, in piena età del bronzo. Sebbene data e luogo della scoperta dello stagno e quindi della cassiterite siano dubbi, si ipotizza
