| The principal ore of tin is the mineral cassiterite, SnO2, found abundantly on Phuket Island. |
| It occurred in weathered material with colorless transparent cassiterite, which is thought to have been derived from the oxidation of stannite. |
| All cassiterite crystals exhibit twinning, and most are black with metallic luster. |
| The principal mineral resource is cassiterite, but exports are at a standstill since the collapse in world tin prices. |
| I have seen Aboriginal people using yandies in the Pilbara district to recover cassiterite though. |
| Arsenopyrite, cassiterite, molybdenite, wolframite, uraninite, and several of the common sulfides have all been observed at various locations. |
