- Cassiterite (SnO2)
is the most important mineral ore of tin.
- Tin is an important
commodity in international trade and is used in hundreds of industrial
processes throughout the world.
- Utilization is in
many industries such as food packaging, culinary equipment,
electronics, tin chemicals, plumbing solders, engineering alloys,
pewter and bronze in music and the arts, dental amalgams, anti
corrosion and engineering coatings, wine capsules and fire retardants.
Tin readily forms alloy with other metals and imparts hardness and
strength. Tin is an important component of solders, since it wets the
base metal by alloying with it.
- The industrial
application of tin is in the following sectors: Solders - 32 %, Tin
Plate - 27 %, Others - 17 %, Alloys - 14 %, P C Stabilizers - 6%,
Tinning - 4%.
- The world tin
production fluctuates between 2.4 to 3.1 lakh tons. The production in
2001, is estimated at 2.49 lakh tons.

account for around 91% of the world's total production. The other
important producers are Australia, Vietnam and Malaysia are the other
