Raritanium Mine
From Ratchet & Clank wiki
A Raritanium Mine was located on planet Fastoon, which was also the first Clank level in Ratchet & Clank Future: Tools of Destruction. It was also the first time Clank could lead a group of Zoni to assist him. It was similar to the way Clank managed Gadgebots in previous titles.
A piece of the 6 missing Lombax Flight Components could be found here.
