Silver cement

[mosfetta]

Hi,
if I cement with sulfuric and steel sponge a mixed solution of silver chloride and other various muds, do I get silver and how do I separate it?

Depends on the other powders.
How did you get this Silver Chloride?

Depends on the other powders.
How did you get this Silver Chloride?

my test:
Various boards, PCBs, contacts and other nitric melt plated metal.
then I added water and hyposylphate, what I get I wash with nitric and cement with sulfuric and steel wool.

This do not make sense to me.
What is hyposylphate?

If you dissolve Silver in Nitric just cement on Copper.
Or at least filter it completely clear and then add table salt or HCl.
This will form AgCl and you can convert it with Sulfuric and Iron or Lye and sugar or other preferred method.

Just a warning, there is very little Silver if any on modern PCBs.

Edit for spelling.

hyposylphate = thiosulphate

hyposylphate = thiosulphate

Can you describe your process in detail?

I have strange ideas that I would like to put into action, but first I would like to understand the function of theosulphate with silver nitrate and with muds containing silver chloride. Thank you

There is no such thing as Hyposylphate.
At least I can not find it.
Please use proper naming for Chemicals.

What about using well proven and tested processes first.
And when you understand these you can start your experiments slowly.

You have not told us anything about your process so I can not help you.

I try to explain myself.
I have tons of PCBs for telephones, PCs and other electronics and I understand that I find little or no silver and gold.
What do I do? I throw it all away or I find some method to exploit the little I can get.
a help a method or something else. Thank you

There is different methods suited for different materials.
There are probably more Gold than Silver in most of it.
You have to decide if it is worth to recover the precious metals.
It is perfect for training but will most likely not be worth it money wise.
So the usual advice is, pick out the richest parts and sell the rest as is.

Then you sort your material and remove all Steel, Aluminum and plastics.
Next cut all "fingers" close and you can process these in a Cupric Chloride (AP) leach.
Dissolve the foils and drop as powder.
If the chips are the correct type they will have more Gold than the plated parts.

Hello.
If there are really a lot of boards, then it’s easier to sell them as recyclables.
Modern electronics can offer little to the amateur refiner.
only if the process is greatly scaled up using smelting, extracting all metals, including copper, tin, nickel and others, there will be a decent profit and not a waste of time and health...
in phones, only if they are not old push-button phones from the late 90s or early 2000s, almost all the gold is in microcircuits, only it makes sense to collect them, here in Ukraine we have two categories of telephone boards: with 6 chips the price is 2.5 times higher than with fewer chips.
chips with a golden corner also have the same cost and content; they are called “with a tie"

the rest is easier to sell by weight to large processors
