Tin is produced from its oxide (SnO2) known as stannite, casserite, or tin-stone, which is not so abundantly distributed as are ores of many other metals. The oldest mines are in England and the East Indies, though ore deposits in Europe and America are now worked. The best grade of commercial tin is said to be from Banca, in the East Indies.
