People tend to rip the copper out of high wattage HID ballasts due to how easily accessible it is, especially now that some grades of copper are over $4 a pound. Fluorescent ballasts and potted ballasts are usually scrapped as is as a "transformer" or "motor".
It's kind of annoying, because it makes HID ballasts hard to find sometimes, because of the "money rush" of ripping them apart...
! But it has a sad ending 
it was an incredible brilliant read, it brung a tear to my eye! didn’t know much of that stuff! It will get a lot more attention than my Belgian one I can tell!
