Fiberglass removing

[Sy-Spark]

I want to strip gold from RF connectors using cyanide, but the thick plated area which is pin of the connector usually coated with fiberglass, burning the connectors will make carbon insulation layer and its not a clean process, any idea for removing the fiberglass from it?

Is it not possible to dismantle it?

No, it's waste of time cause it's mechanically pressed not threaded, also am talking about tens of kilograms from this material.

In past I was using Nitric-sulphuric leach to get full gold yield, but I stopped dealing with large acids quantities, then I processed them by smelting and copper cell but zinc vapors during smelting really a big issue so I decided to only deal with them using cyanide method. The different between cyanide method and the full gold yield is about 25% because the thick plating is on the coated pin inside the connector.

Fiber glass are not soluble in any acceptable acids.
Neither are epoxy.
Pyrolyzing and ashing will be the only option besides cracking them open manually.

Do you think burning them then leaching them in NaOH will remove any carbon insulation on plated copper so I can use cyanide?

I'd test with one at a time to see what works.
But I see no upside with NaOH, it will not touch the Carbon.
