Yttrium (Y #39) is the next element on the periodic table for my APEX mineral collection.
Yttrium Minerals - There are many Yttrium minerals.
Bastnasite-(Y) (Y(CO3)F) with 53% Yttrium is the obvious APEX Mineral. This is my first mineral with a "generalized" formula. The more common forms of Bastnasite are Bastnasite-(Ce) (Ce(CO3)F) and Bastnasite-(La) (La(CO3)F).
All forms have little difference in physical properties.
- 17 metallic elements that have very similar properties. Despite the name, these rare earth elements are relatively plentiful. You just can't find useful deposits hence the "rare" description.
- When more concentrated rare earth deposits are found, most of these elements will be diffused throughout the deposits.
- It is extremely difficult to separate each of the 17 rare earth elements from each other.
Yttrium and its compounds were unknown before modern times.
