Question on rinse process

[Yggdrasil]

What the heck happened? Copper sulfate with copper sheets and now this?

What about waiting for replies before you do something?
I'm not very proficient in cells.
But what you will need for your plan is an Electrowinning cell and they are constructed different.
They often use a felt like cathode and have much shorter distance.

Have you considered a glycine leach?

I have not. But I am looking into it. Seems promising.

Why did you leech your black sands with thiosulfate? Have you used it before?

My i advise to look into "how to get your gold out" before you dissolve it.

What do you mean get out before dissolve it? Around 80 percent of my gold in black sands is 200 mesh and smaller in a 10 bs to 1 gold/silver ratio. If you know of a way to get 95% recovery or better of both Au and Ag then I am all ears. Gravimetrically with three types of devices have proved very limited recovery. And glycine is to expensive to afford to use on such a large amount. So thiosulfate seemed to be the one I would try.

Leaching kind of implies putting pm's in solution to concentrate and isolate, i.e. dissolving. So how will you get it back out of solution?
Like getting dissolved gold out of a thiosulphate solution. if you don't know how, then why dissolve it and not just give it away? Unless you have a use or customer for pm's dissolved in thiosulfate.

I read somewhere to cement dissolved silver on steel wool, but how exactly; at which pH or with which pretreatments or additions, no idea.

To me it sounds like you put your money in a safe without knowing the combination of the safe?

That should be check number one, right?

I figured out how to get all metals to drop out of thiosulphate solution and it was by pure accident. Going to mix up and make sure it was not an outlier. Then I may share because it will be a breakthrough that nobody has been able to figure out. It did the same as smb does to hcl solution. Will try again this weekend.

not sure but i use sodium thio sulfate to turn crusted silver chloride from silver coated gold after AR and it turns the silver chloride into silver oxide which breaks apart from the gold with agitation then alloys AR to attack the remaining gold i have into solution.

Why are you using it ?

Trying to use thiosulfate for leaching of super fine gold in black sands concentrates.

I am curious about the results. Did you try it again?

I did it again and it dropped out again. Going to smelt it and see what I get for metals. May just be residues not sure yet.

I am planning to experiment with Sodium Thiosuplhate as well to selectively leach gold plate from connections. Looking forward to your results

Hi mate, can you please let me know what you did to leach in thiosulphate solution as i am trying many different experiments. like did you add small amount of copper sulfate then add few spoon fulls of thiosulphate then add couple spoon fulls of ammonia sulfate and use ammonia as the liquid. then maybe zinc powder or copper to drop the metals. i just need 1 set list to follow and not guess this or that if that makes sense haha

I just did a leach and used 5 volts of electricity to leach around 1 Oz of sterling. And it leached a 4 gram gold necklace also. But it ate up my stainless cathode. So I have a little bit of a mess. It was a long process and dirty because of the sulphate. Going to strain today and see if the silver and gold are in solution. Will post when I figure it out.

I am going to start another leach when I get the sodium nitrate I ordered. Will try and touch base about it.

Thanks for that I have also tried with a leach an added volts. I used 2 stainless strips and yes 1 of the pieces of stainless was getting eaten up. It started coursing some silver layer on top and the solution gets real dirty. It almost looks like iron is forming in solution but is like spongey and floats around making a big mess
