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.

The rare earth elements are all metals, and the group is often referred to as the rare earth metals.. These metals have many similar properties and that often causes them to be found together in geologic deposits.are earth elements are not as rare as their name implies. Thulium and lutetium are the two least abundant rare earth elements-but they each have an average crustal abundance that is nearly 200 times greater than the crustal abundance of gold (1).
