I have no idea of the scale, except that rare earth element production appears to be about 250000 tonnes per year.
- jacquesm 4y agoA typical magnet manufacturing installation is a few hundred K of Capital expense. You need to have a way to create blanks and then you need a way to magnetize the blanks. The usual method in a nutshell: - combine the powdered raw materials in a die - compress the powder to create a blank - coat the blank to prevent oxidization - magnetize the blank using a powerful electromagnetic field - QA to ensure proper field strength and inspect for damage I wonder what the hang-up here is.
