The US DOE prepared a paper in February; my first time seeing it, so it may have been discussed here previously, as February is a big "get out the house" month for me.
Excerpts related to thread:
The apparent fate of the much-ballyhooed "Toyota magnet" revealed:
-----------------------------------
The magnitude of waste associated with NdFeB manufacturing aka swarf (much has been gained by the use of extremely fine wire saws to minimize kerf losses):
----------------------------------------------------------
Updated estimate for magnet weight per MW used in turbines and a clear specification of grade of the current grade.
-------------
Current estimation of NdFeB magnet production by country:
I'm sure you can guess.

Another direction I have thought Lynas might go with the LAMP was downstream towards the metals. Not so good news on that front (but with a caveat - and remembering all those unused utilities at the LAMP). The paper has a short section on how it's done and how much it costs per kg to do it for those interested; don't miss the Appendix which contains further material on the subject of Dysprosium electrowinning.
last but not least an interesting table that begs for a posted definition of "significant":
