Refining of Niobium and Tantalum | Gold Refining & Metal …
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.
