Neodymium is a material that is obtained by refining bastnaesite in the Ore Refining System. Specifically, bastnaesite ore can be mined using the Mine Extractor in 15-16 minutes with level 2 mine software and then refined in 7-8 minutes. Alternatively, a bastnaesite necklace can be recycled; this will yield a bastnaesite gem, which can then be refined to gain neodymium 1-2 minutes. Bastnaesite ore, gems, and necklaces have a stack limit of 50; neodymium has a limit of 300.
Neodymium is used to produce the following items:
