2023年6月10日 La cassitérite est un minéral composé d'oxyde d'étain (SnO2) et est le principal minerai d'étain. Il a une densité élevée et une dureté de 6 à 7 sur l'échelle de Mohs, ce qui le rend relativement résistant aux intempéries et à l'érosion. Le nom "cassitérite" est dérivé du mot grec "kassíteros", qui signifie étain.
