r/chemistry - Dissolving Copper Wire Insulation - reddit

Using solvents to try and strip off the insulation is probably going to take longer, even if you do find a solvent that works. More to the point, you will end up with a load of nasty contaminated solvent waste to deal with, which could easily be far more expensive than the value of the scrap copper itself.

Hydrometallurgy - Wikipedia

Hydrometallurgy is a method for obtaining metals from their ores. It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. Metal chemical processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy and molten salt electrometallurgy.
