Anyone know where to get them? Thanks

PavePrince,

You should test your yellow liquid with stannous chloride to be sure you are on the right track. If so I would use aluminum to cement everything out of the pregnant solution and process the powder that precipitates out.

Start by rinsing the precipitated sludge several times with boiling water. Next treat the sludge with hot 50/50 nitric acid. Be sure to test the resulting solutions with stannous so you don't throw the baby out with the bath water. Rinse three more times with boiling water, and then dissolve the remaining sludge with AR or HCl-Cl. When the remaining sludge is all in solution test with stannous and precipitate as required.

Steve (Noble Metals),

I can get the requested item if you PM me.

where can i buy some nitric acid

 

[NobleMetalsRecovery]

Does anyone know where to get a "Fusilica cup" ?

 

[lazersteve]

Steve,

It's just a standard fused silica crucible. I can get them if you want one.

PM me for more info.

what would happen if a person just used salt water and peroxide without the inside cup? What purpose does the cup serve other than a smaller bowl... thus less wasted chemicals.

 

[aflacglobal]

The bowl has a 5 micron pore size. It only allows certain size ions to pass thru it. Thus blocking and seperating out the unwanted metals.

banjags, i did that once in a pyrex beaker. greenish mud clouds form and swirl around. i used a carbon rod cathode. black residue would cling to it. this according to the hoke book is i think gold. when you disconnect the current though its still on the rod but comes off easily with a spray bottle of water.what i want to know though. what is in the green clouds? gold ? silver? copper? im desolving gold rings with stones in them . the stones fall out after some time. its preatty cool. im still confussed on how to re trieve the gold though. one time i filtered the mud from the solution. it was dark grey. i dryed it out added borax , nuked it with my torch. and got a rich gold colored bead. what i want to know is . was there silver in my bead or did the alloys in the ring filter out into the liquid. or was it in the mud ? heeeelllllllllpppppp mmmeeeeeeeeee!!!!!!!!! some body. the rings were all 14 karat yellow gold . about 25 grams worth. didnt get much gold though. about 1.8 gr or so. so i think i had substantial loss. i thirst for more input and guidance.

oh ya i tried the salt cell with gold rings using a flower pot i got from hobby lobby (no hole in the bottom). this worked well because the carbon rod did not get bound up with deposits from the rings. i also tried to bag the rings to catch the pieces of gold that did not desolve or to catch the gold mud but this was a messy pain in the a$$. the nylon tears. and leaks into the solution defeating its purpose. the nylon seems to soak up some of the metals so im going to nuke the nylon to see if gold , or some kind of metals appears. also the solution during this process gets up to about 125 to 130 degres ferinhite (sorry for the bad spelling). there is lots to discuss. hope we can figure it out.

Let me check if i understood all or i got (probably) something wrong...

[img:640:480]http://www.monetaio.it/portal/Collezione_Privata/capito.jpg[/img]


Where:

1 - Is simply a stainless bowl with no soulders.
2 - Is a Ceramic Crucible. Can i use a Graphite one too ?
3 - Is water + 10 mL of hydrogen peroxide 3% per liter + salt (how much?)
4 - Is a stainless clamp where i put my solid gold to liquify
5 - Is water + salt without iodine (36 grams per 100)


Can you check if all this is correct, and eventually correct me where i'm wrong ?

Thanx.

 

[lazersteve]

Everything looks good to me.

You can experiment with the amount of peroxide needed.

All salt solutions are saturated = 36 gm/100 mL


I would not allow the SS anode clip to enter the anode cavity. Lower the gold only on to the liquid. Make a gold hanger for this or make your gold into an anode with a hook shape.

Do not use graphite for the membrane.

The dissolved gold may go into solution or may leave gold sludge. Experiment and test with stannous to determine how the gold reacts.

I probably should build one to test everything out.

Maybe can i solder a silver wire on gold ?

That's ok.

Awaiting your PM!
Ty.

I would use a gold hook to hang the karat gold into the cell. Melt your karat gold into the shape of an anode and include the hook in the shape. When the anode decays the hook will remain undissolved. Add this to the next melt for the new anode. You can connect your positive lead to the hook.

Send me your mailing address via PM and I'll get you a quote for the tin metal.

Here is a great site for filter bags that can be used for cells and bagging plates. ( cheap too ) :arrow: http://www.filterbags.com/filter_bag_pricing.htm

 

[Froggy]

The filters are cheap but the housings!!!! :shock: They claim the housings are for acid but stainless?

I made lot of tests, and i can say something about this now.
It works to dissolve solid karat gold: but u'll got silver chloride in solution (if u use tap water cleaned up with Cl), not only putting inox in it...

But it can be usefull to store AG in chloride form, and not dissolved in liquid (very less volume).

 

[ALPHABiT]

I would think that the voltage would be less, for a given amperage, the closer the electrodes are. The solution has a certain resistance, per unit distance. The closer the electrodes, the shorter the electron path.

I used 24V 10A . 10cL (not mL) of H2O2 per liter of H2O+salt.

50 grams in a bit more of 1 hour dissolved.

Suggests to work safer ?

This question may sound ignorant ,but here goes ,I am new to this field and overly excited about trying to do this . I have gathered up some materials and have a basic IQ ability .A little concerned about safty and health risks in working with all this .NEED GOOD INSTRUCTION from real people that are succeeding at this . Can any one dirrect me or give advice on where to start. ??? I have gathered CPU's finger boards , and some gold plated jewelry ,and silver plated materials .My experience is in melting and molding silver into ingots . I have the desire , have been ripped off from ebay information and trying to find real help!.Dont mind paying to learn ,but want to learn the best info that is safe to use :roll:

 

[Noxx]

Don't pay anything to learn. Everything you want to know is here and free.

I would suggest you to take your time and read a lot of the posts already on the forum. Then, if you have any questions, I'll be glad to answer.
