Cassiterite has been used as a major source of tin for centuries and was one of the first metal alloys. The name "Cassiterite" is derived from the Greek word "kassiteros" which means "tin". It is also believed that this word was derived from Cassiterides, an ancient geographical name of islands off the western coast of Europe.
