Sources of tin. Tin is relatively rare, making up only about 2 parts per million of the Earth's crust, according to the U.S. Geologic Survey. Tin is extracted from various ores, chiefly from Cassiterite (SnO 2). The metal is produced from reducing the oxide ore with coal in a furnace.Very little tin has been found in the United States, much of it in Alaska and California. According to Los Alamos National Laboratory, the metal is mainly produced in Malaya, Bolivia, Indonesia, Zaire, Thailand and Nigeria.ery little tin has been found in the United States, much of it in Alaska and California.

Tin is a chemical element with symbol Sn (from Latin: stannum) and atomic number 50. It is a post-transition metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide, SnO2. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4. Tin is the 49th most abundant element and has, with 10 stable isotopes, the largest number of stable isotopes in the periodic table, thanks to its magic number of protons.
