Question on rinse process

[shadybear]

I have read never tested that the black sands dont have gold in them, but
stuck to or mixed in just very small.
Freddy Dodge uses a shaker table for this on tv
How about some form of magnetic seperation

Did you cement it on Iron?

Copper

 

[Yggdrasil]

Copper

Have you tested the material for Gold content?
Assay?

Yes. Assay and lab tests. 2 g per ton gold 7g per ton silver

 

[Fettigconstruction1@gmail]

Yes. Assay and lab tests. 2 g per ton gold 7g per ton silver

In the pile. This is cons from 100 tons so should produce 200g gold and 700 grams silver

Have you tested the leach liquor to see if it has dissolved the Gold?

I would but not sure what to use. Everyone says stannus doesn't work in thio or alkaline solution

Acidify it and use Stannous?
Unless there might be any adverse reactions regarding the Thio?
In Cynide this is out if the question of course.

Well I was thinking that but reading research it mentions if you adjust the ph it will hold the gold in solution? Maybe bs. I am wondering if cementing with something more reactive than copper? I have some galvanized metal that has zinc? Or I have aluminum powder. But then get all the junk too..

When my copper oxidized on accident it drop quite a lot of silver out. So not figuring what to do. Strong base anion beads.. do they absorb all metals in solution or only nobles?

I used stannous and this is what it looks like. Says Pt. Unless it's a reaction to the sulphur?

I don't think Pt.
Better either use a cotton bud or a strip of paper.

The question is if your leach reaches the Gold and if it do actually solubilize it.

Your initial Stannous test do not support this.
So unless the Gold are in solution there is no point in cementing.
All other metals than Copper will drop many base metals as well.

By the reactivity table gold silver and pgms should only come out with copper. I didn't acidize first, just put the stannous in since it is hcl. Maybe that doesn't work.

 

[SRM]

As an alternative, take 1kg of ore, assay the sample, treat with chosen lixiviant/process, assay the tails and compute your extraction/recovery.

The precious metals come out with "all" base metals.
But the base metals don't cement on Copper.
If I'm not mistaken, pH need to be lower than 4 to let Stannous work properly.

I guess I don't understand base metals? The purpose of making the fancy bubbler with copper sheets that is on here was to only precipitate the PM only to the bottom of the container.

Early morning here.
The PMs will come out with all metals, but Copper will only cement out the PMs.
For instance, Iron will cement out the PMs plus Copper.

So got a question. Bought a DC power supply. I have gold in solution. In a thio solution. If I add the recommended amount of copper sulfate into the solution, can I do a copper anode to copper cathode and do the ion transfer. Will the gold that is in solution drop out?

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