Cassiterite is a mineral composed of tin dioxide \left(\mathrm{SnO}_2\right). In this mineral, the oxidation state of tin \mathrm{(Sn) } is +4(\mathrm{IV}). Each tin atom in cassiterite has four oxygen atoms bonded to it, resulting in the oxidation state of  +4  for tin.

Stannite is a mineral composed of a complex sulfide of tin, copper, and iron. The oxidation state of tin in stannite can vary. It can exist in both the+2 (II) and +4 (IV) oxidation states. Therefore, the oxidation states of metals in stannite are II and IV.
