how do i separate, recycle, the silver from copper tinned wire and is it cost effective - chemical or smelting ?

I have 25,000 feet of military spec marine grade 26 awg high strand count 3 conductor helix braided shielded in plastic sheathing.

I have no idea how many ounces of silver are involved but can guess at the copper, which is worth much more un-tinned and brite.

some have suggested crushing it to remove the plastic as the 3 conductors are also sheathed in plastic but there may be enough of this for me to tool up to do it all chemically or burning it using the right filtration??

thanks,

Sell it on ebay for us boaters - greater return.

I am a wire chopper. We run into military grade silver wire all the time. I have to send it to a refinery. Basically lose the copper value. It offsets the cost of the process. If there is a chemist on this site, please respond. I too would like to cut out the middle man!!

When I scrap cable that is maybe going to be expensive I strip the plastic by hand with a knife. If its just tinned you can see in a cross section when you cut it that the inside is copper and usually the scrap dealer will give you a ok price. Usually burning it ends badly and if they see charred metal it is generally frowned upon. They do have stripping tools as well if you have 25,000 feet it may be worth it. Also save the shielding it is usually a decent grade and though it is light it can be worth ALOT. But basically if you do it by hand you will get the best results, it will be a pain and may take a while but worth it in the end. Maybe take a small section (a foot) and see how much the scrap guys will give you and go from there.

I would be very surprised if the wire was coated in silver versus tin. So you should make sure before you waste any time. Tin is magnetic (even just a thin plating) while copper and silver is not... and if its tin, it isn't worth the time or effort to try and remove. Just sell it "as is" to a recycler. They won't give you any more than #2 copper prices.

If the wire is in good usable condition you might be able to sell it on E bay for more than what the salvage price would be.
Strip all the insulation off and then take the wire to be recycled. You'll get more per pound without the insulation on it. The small amount of tin that may be on the wires won't effect the coppers value and won't be worth the time and effort to strip off.
The usual way of stripping cable in an environmentally friendly way is to crush it between rollers, so the wire cuts the insulation to ribbons.

I doubt its silver,its just tin, and in a very thin layer. Its not worth recovering separately. The copper would be used in a bronze, so the tin would actually be useful.
