Non-Chemical Recovering gold wire from ash with mercury

[mrpazu]

Hello Mindenki! Sajnos nem tudok angolul Google fordítóval olvasom a fórumot.
Kb egy éve feloldottam pár gramm aranyfóliát higanyban. Továbblépni nem mertem.
A lombikban aranyamalgám, higany maradt lezártam vízzel és ledugóztam. Olvasva a fórumot
kísérletjelleggel elővettem és réz 2 kloridot adtam hozzá. A lombik alján aranycseppek, homok, szürke por van.
( volt benne szennyeződés ) Higany eltűnt. Valakinek ötlete mi a teendő?

Üdv mrpazu!

Great thread, thanks for sharing Kurt. I have been thinking about Mercury for recovering bond wires for a while now. My limited research has indicated that a pipe-retort is probably the way to go to after you finish the amalgam.

For all the contributors saying that there are better ways to process super fine bond wires, are you just referring to HCl -> Incinerate -> HNO3 -> Wash -> Aqua Regia ?

Nope I would add a ferrocyanide/cyanide leach to that list. it's pretty much far less toxic than messing about with mercury. You've got to ask yourself which method is still used worldwide out of the two. Mercury or cyanide?

Forget about the mercury. It is the most hideous and insidious element when it comes to the very young or unborn.

FORGET ABOUT USING MERCURY :!: :!: :!:

Per the underlined Thinking about using mercury & doing it are two different thing

This is something I did a long time ago when I was first learning about all of this here on GRF - I was advised back then not to use mercury & I took that advise

The mercury I used to collect the bonding wires in this thread was the first time & the LAST time I used mercury

There are better & SAFER ways to get your gold :!:

My advice - think about it all you want - just don't do it :!:

Hi Kurt,

Thanks, for your feedback, I was a bit confused by your reply at first, I didn't realize the thread was from 5 years ago at first!

Overt time I have gotten reasonably good (in my opinion) at pulling gold from E-waste using only the wash -> Chemically remove base metals -> AR path, I was hoping that the Hg may be a more efficient way to go, but based on the recommendations of the seniors here I think I will bypass it.
