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%.
