Here's a patent for everyone who wondered what to do with all those black, yellow, and orange surface mount Capacitors. I believe the orange ones have Niobium, instead of Tantalum.
NOTE: in this patent it mentions the use of Hydrofloric and Oxalic Acids. Do not use the Hydrofloric Acid method. You can use Oxalic Acid, which is still dangerous, but safe if proper safety measures are used.
Hope this can be of use to members of the Forum.
Method for refining hydroxides of Niobium and Tantalum: :arrow:

If any of our more knowledgeable members check this out, your feedback on the feasability and safety issues would be most welcome.
Good luck, Gorfman
