Looking for alternative means for pickling up palate-plated copper wires

[Francescoitaly]

A few months ago, I opened a topic in the forum seeking a method to remove palladium from palladium-copper wires without attacking the copper. I found it.

However, the method I currently use consumes a lot of reagents and emits many toxic gases. I would like to ask for your help in finding an alternative approach, and I am willing to share with you the method I currently use.

Sounds like a job for a copper cell. The palladium would be contained in the slimes from the cell.

I can't remember the thread.
But why are you not posting this in the same thread for continuity?
Anyway is it a point that the Copper wire can be reused?

Hmmm - well - we can't really give you any suggestions on "alternatives" if we don't "first" know what your current method is

So yes - please tell us about your current method --- & pics are always good

Melt the wire into a bar. This bar will, if your explanation is accurate, be a mixture of copper and palladium. If the copper content is above 90% this material which we can now call an anode is in the perfect form to serve in a copper sulfate electrolytic cell. The cell will produce electrolytically pure copper and in the anode bags will be a black mud of palladium copper slimes. This electrolytic process allows you to concentrate the Palladium into an easily purified end product.

It is more than 2 tons, so the cell would need to have a very large volume. Currently, I use HNO3 diluted to 50% and keep

Hmmm - bem - não podemos realmente lhe dar sugestões sobre "alternativas" se não soubermos "primeiro" qual é seu método atual:revirar os olhos::revirar os olhos:

Então sim - por favor, conte-nos sobre seu método atual --- & as fotos são sempre boas

Atualmente, uso HNO3 diluído a 50% e imerjo até que todo o paládio seja removido dos fios.

How is the recementing of the Pd onto the Copper going?
Is it an issue?

You could add additional copper and cement out the Palladium with Silver but you will forego a few thousand pounds of copper which is valuable as well.

Reduce to slimes by electrowinning away the copper. Dissolve the slimes in Nitric and drop the PMGs with DMG. Don't see why that wouldn't be efficient.
