Last chapter of recovery process.

[Brad72]

Good afternoon,

I want to start out very informative forum my gold bible for reference. I like how the bull is cut and no sugarcoating ,as I most likely will experience this with my first post and so on. In 2009 I started a ewaste business recycled over 5 million pounds from 2009-2015 when sold the company most was CRTs then I had no idea on how or what gold recovery was I just sent all those early Pentium boards all the ceramic chips everything of value as I had business accounts,schools, hospitals endless supply I let all that gold and other precious metals be recycled but I was late to the party for gold recovery. I even had a customer dropped off Two coins he had said like a vanity coin and was cleaning out his sons closet said they came from China or Japan. I just sat them on our bench for years they sat there sold the business remembered years ago about crypto mining I don’t even know when it was 2011 or 12 just remember a gold coin with a big B in the center. My loss big time there.

My brother always told me I had a gold mine with all my accounts and recycling thousands of pounds, fast forward to last fall I still have retained some accounts not near the volume but I started getting into gold recovery so I did very little research and jumped in broke down pounds of equipment bought some mureactic acid with hydrogen peroxide and started soaking and making gallon jugs and every glass jar with memory, PCBS. hard drives,etc. I am in Illinois so Winter hit and had to put up shop until spring, I have gallon jugs with blue tint solution,I had a pickle bucket with gold recycled sitting in Mureactic acid hydrogen peroxide. This week I have been able to get out and all winter read Hokes book two or three times on this forum so many questions.

I realized I needed the correct chemical process after researching all winter. I found with what locally is called Hi-Yield Ammonia Calcium Nitrate I have tried it with mureactic acid or by itself. Some of my solutions are emerald green I have successfully dropped using stump it or iron out chemicals. Today I had emerald green on bottom Brown on top solution in a small jar, many all have gold as my filters are yellow and I get to the point of last process I just want to make sure my final processes are correct I have solution in various final stages.

Sorry for long winded story so many videos make it look so easy

What is your question?

Is that type of nitric acid that can be used or how to make it with it if even possible.

 

[haveagojoe]

Not recommended.

If you have lots of solutions at different stages, it's probably best to get them all to the same stage before moving forward. Get all your gold foils together in a jar of water and go from there.

It's not necessary to use nitric, there are other ways which are less dangerous and have less problems. You need to be very clear about what you are doing with each step, and why.

The gold foil almost ten pounds of pc66 to PC133 has on been dissolved and sat for the winter

 

[haveagojoe]

Are those RAM?
When you say dissolved, has the gold itself dissolved and disappeared into the solution?
Or do you have tiny flakes of gold floating around? We call those foils.

No just dark brown solution when stannous test shows gold in solution you can see it red tint get it on your hand turns yellow of when filtering that batch has been sitting in a pickle bucket since November in mureactic hydrogen peroxide solution. If I filter it comes out either dark emerald crystal clear solution or yellow

Ok so, first mistake, you don't need to use hydrogen peroxide. If you do use it, you only need a tiny, tiny amount, like a few drops. If you use peroxide the gold foils will dissolve and you don't want that at the first stage. You only want to dissolve the copper which is underneath the gold, so that the gold foils float off, then you can collect them in a filter. Instead of peroxide, use an aquarium air bubbler. This will do the same job of adding oxygen to the solution, but it won't add too much and dissolve the gold.

But since you added a lot of peroxide, it sounds like your foils have dissolved, the only thing you can really do now is first filter your solutions, and then in the filtered solution put some clean pieces of copper. After a while the copper will go black, the black powder which collects on them is your gold. We call this cementing. It will take a long time to cement all the gold out.

Then you can clean the black powder off the copper pieces with a toothbrush, brushing it back into the same container, and then filter the solution again to collect the black powder in the filter. Then you can wash the filter off with water to collect the black powder in a jar.

When you have collected all the black powder, come back and we can help with the next stages.
Don't throw away the used solution, for now just put the copper back in it to try to get any more black powder to come out. You will be able to reuse it again in future, but just concentrate on one thing at a time.

Make sure to wear gloves when handling the acids.

I will post tomorrow pictures. This one picture I had had the brown color on top and green on bottom, added a little HCL and this is we’re it is

Thank you for your time to help very much appreciated

Ok a couple of things:

Firstly don't do reactions in sealed containers- the bottle shouldn't have a lid on. Use a larger container and never fill it more than halfway full.

Secondly that looks like your kitchen. Not a safe place to do this kind of thing. Reactions produce fumes, and the solutions can contaminate food. Work outside, and keep the acids in a secure place away from where kids or animals can get to them. Don't get the solution on your hands- if it's not strong acid it may not burn, but it still contains dissolved metal which soaks into your skin and can cause health problems.


With this bottle, empty it into a bucket or similar container and add a piece of copper. Clean copper waterpipe will do, hammered flat, or some copper wire. A small piece will be ok since there probably isn't a huge amount of gold in the solution. The copper needs to be completely submerged, not sticking out. Cover the bucket loosely and leave it for a week or so, stirring the copper around occasionally. When black powder builds up, knock it off to the bottom of the bucket or brush it off with a toothbrush to expose the copper again.

If you have other solutions which you got the same way, you could combine them together to get all the black powder at the same time. But only if they are the same and don't contain other chemicals.

Welcome to us.

Your first text are a bit hard to sort out, but for clarity.
You mixed the Nitrate with Muriatic acid (HCl)?
If so you have what is called poor mans Aqua regia aka AR.
In order to make poor mans Nitric you need to mix the Nitrate (dry) with strong Sulfuric,
cool it down and filter out the extra salts.
There are descriptions in here.

Anyway I recommend doing as was told in Hokes book.
Small experiments to become acquaint with how the reactions behave.

 

[haveagojoe]

mix the Nitrate (dry) with strong Sulfuric,

Possibly not a good idea with calcium nitrate: https://goldrefiningforum.com/threads/making-sodium-nitrate.1330/post-18208

He can find other Nitrates I guess.

Edit to add:

If he wants Nitric, Sulfuric and Nitrate is his "only " option unless he can buy the real deal.

 

[haveagojoe]

It seems like he already dissolved the gold once by overusing peroxide in AP, I was going to suggest going that route again when the time comes

Try HiYield sodium nitrate. It is easier to work with than the ammonium nitrates. Use it in the muriatic or hydrochloric acid on a lowish heat. Us only glass that is made to be heated. By using heat you can forgo the sulfuric acid. Start with small lots first, if something goes wrong, you have a smaller mess to work with.

Then it will be AR not Nitric.

Yes. I didn't notice he wanted nitric at the time. The ammonia in a nitrate still is more difficult to make nitric from for me. It causes a cooling effect that makes it harder to convert to nitric acid. Potassium nitrate works well as does sodium nitrate. Calcium nitrate does but seems a bit more difficult to separate from the resulting residues. If he has access to HiYield brand their sodium is easily accessible as for making nitric or poorman's AR.

We had a discussion a few years back where I lifted the possibility to use Calcium Nitrate with the Idea that it wold be a solid and one could just filter it.
There was some disagreement because it was holding on to the Nitric and was hard to separate.
Since I have not had the chance to try it, I put my case to rest.
