Tin is produced by reducing the ore with coal in a reverberatory furnace.
The only mineral of commercial importance as a source of tin is cassiterite (SnO2), although small quantities of tin are recovered from complex sulfides such as stannite, cylindrite, franckeite, canfieldite, and teallite.

用carbon reduction!!!!
因為佢係SnO2 when tin reaction with oxygen.
之後可用carbon take away oxygen molecule to form Sn!
