Gold Recovery via Copper Electrolysis - Part 1 

Finally......LOL. This is why I keep you around. This thought process has been rolling around in my head for some time now. Awesome brother. Keep up the good work

Brilliant video, thank you! Can't wait for Part 2! Take care, Poo

That's an incredible and new (for me) way of gold recovery!! Have a GREAT Day!!!

I've watched plenty of vids - you for sure make the easiest to follow/absorb info vid i've seen in this neck of the yt woods 👊

sincerely happy you posted this that's a great setup I would over think the crap out of it and still not come up with that its brilliant in my book I have been wanting a new "mission" to use the power supply I used for my silver crystal experiment thanks

Off to Part Two I go! Dankie... lekker om te sien hoe jy dinge doen!👍😁

As usual, GREAT VIDEO. It makes me want to try it. Popcorn is ready for part 2, LOL.

Thank you for making this video.

I love it, great video!

great info video thanks for sharing most use this the next time i recover gold from pins

The density of copper is 8.96 g/cm3 or 0.324 lb/in3. You can work out the weight required from there. I don't have any pins at the moment but this looks interesting. Great work as always.

Excellent, I look forward to the rest of the process, well done. 👍

Have you tried using solar panels to produce the DC for the hydrolysis? It works fine all day long on sunny days anyway.

Good job, and this is the best way to deal with pins so that they benefit from copper and provide acids but I ask maho 's question and the correct voltage for copper

If you use a titanium anode basket inside a filter bag the copper plates across to the cathode and the slimes stay in the bag. You can keep topping up the basket with copper mixture and swap out the filter bag to recover the gold etc

Most of the pins I come across are made from some kind of yellow brass, not copper. Good technique for copper pins. Thanks for excellent video.

great idea from the science to know the extraction of gold and copper specially the technology

I like that noisy cow. She does not explain things all that well, but she really enunciates and emotes!

works out to about 130mA per sq inch. Good video, thanks for posting

i do a lot of electroplating copper, and it's a very similar setup. in my experience, the most cost effective source for copper sulphate crystals is by the 50 lb. bag from the agricultural supplier- it's used to prevent algae in ponds and to disinfect cattle feet. the cheapest sulphuric liters seem to me to come from make-your-own-at-home biodiesel chemical suppliers.

Very very good job ....I appreciate your idea....very nice 👍

Is it possible not to melt the anode, but to dissolve just a handful of contacts?

I love your 📹 video well explained very informative

a titanium mesh basket (you'll have to stitch or spot weld your own from wire) helps hold all the last little bits, once your annodes are almost gone. get a fine enough mesh going, and you can just drop plated pins directly into that.

When you do reverse electrolysis using sulfuric acid outside , what should the temperature be? What would be the lowest temperature and still be safe?

Great stuff

1. I tend to pull the Steel and peel the copper off after a day by slightly bending the center of the steel. Allowing the copper to accumulate to long makes the copper very thick and difficult to get off. 2. You can always add more copper to the pins to reduced the percentage of other metals. 3. I like watching the molten metal get poured, and just being all melty and pretty...

Very interesting solution to the issue. Would it be worth havingh some kind of receptacle under each anode to catch the slimes - I suspect it will make cleaning the cell out at the end much easier.

very nice

the pins are often brass so the acid h2so4 gets full of zinc solution. A chloride solution with cu2+ will work better. A divider of cloth will stop the contamination of anolite & catholite solutions. agitation is good to get the sludge to drop off the anode. Anodes can be cast in the frog of bricks which have been pre heated.

You can skip the pin melting step if you use a titanium pan for the chip pile. You will end up with more foils and less slimes to deal with. I also used the "waste" solution from a Poor Man's Nitric process as the electrolyte. 5v power supply and about a 1/2 square foot SS cathode.

cool 👍😀👍

very good video thank you very much

Very informative and credible. Many thanks

cementation separates which elements? and what other chemicals can be used besides sulphuric acid?

How or were u get copper to use an witch one on the copper hot or ground

Hi very interesting video and other then the recovery of the gold you recover also the copper that is use full for other procedures, is there any way to recover the copper dissolved in muriatic acid by Electrolysis

How could you increase the A with keeping the V between the 2 plates same? You increase the space between the plate to increase R?

Great video mate. I thought bout doing this myself. I haven't gotten around to it. Question though, in my research of the copper sulfate electrolyte solution I seen that you can add 0.5ml per gallon (US) or 3500 ml of solution. Have you read anything like that?

Waiting for Part 2 sir

If you put a plastic divider with holes in it you could segregate the two precipitate slimes. That way yoy would have gold waste on one side and copper waste in the other, then you could retrieve them one at a time im thinking something like a plastic wall that has holes in the top so the electrolysis will still transfer a current , then solid wall at the bottom, then glued in or even melt sealed to the container, then you would have two separate piles of slimes.

what happens if we exclude HCL from the process. Can the system work?

When is the second part? Can you make a text file?

Вторая часть будет? The second part will be?

Can I contact you to get so advice from you about recovering gold plating from new boards that have never had any circuits attached to them& so other questions as I am about to start my first gold recovery’s from all the types of stuff I have

32:00 I think the Ampere short circuit thru the electrolyte . You want the copper particles to move the distance, not the electrons .

Can we separate gold from aqua Regia by this method?

Could you use copper nitrate instead of copper sulfate?

Метод рабочий, но есть несколько нюансов. Во-первых, при плавке меди с золотым покрытием много золота переходит в шлам. Во-вторых, при электролизе нужно учитывать, что лигатура содержит никель в подложке, который так же выпадет в шлам. По затратам на газ и электричество проще все растворить в азотке или снять позолоту смывом в царской водке. Но как с точки зрения эксперимента - поучительно. The method is working, but there are several nuances. First, when melting copper with a gold coating, a lot of gold turns into sludge. Secondly, during electrolysis it is necessary to take into account that the ligature contains Nickel in the substrate, which also falls into the sludge. For the cost of gas and electricity is easier to dissolve in nitric acid or to remove the gold by flushing in Aqua Regia. But as from the point of view of experiment - it is instructive.

I like the look of this to remove copper from smelted dore bars with copper as the major basemetal fraction. It saves on acids. Im wondering if palladium will be dissolved and cemented out as well though?

For those who cannot melt copper pins into bars for the anode, instead could the pins be put into a porous bag with a connection to the power supply and dunked into the electrolyte? Similar to using silver shot or cornflakes in a silver cell.

what if you use Copper mesh (16 by 16). would that work/

I'm not sure if i missed it: What was the voltage across the electrodes over this run? It's surely somewhat current-related, isn't it?

So what happens if you have iron, Nicole and other metals in the pins?

Hello...do you think we can separate copper from nikel with this methode? As copper sulfate and nickel sulfate both are soluble...Otherwise if any idea to separate this 2 methal with electrolysis, i am very interessted...

where do you get your concentrated sulfuric acid from?

any kind of stailes steel i can use or is an specific SS?

👍

what SS blank did you use? was it 304 or 316? thanks

Thanks for sharing your knowledge, you mentioned 75 grams of CuSO4 per liter, do you mean 75 of copper as CuSO4 which mean you will dissolve about 300 grams of CuSO4 or you mean 75 CuSO4? Cause I read in different sources that copper content should be 50 grams per liter that mean we need 200 grams of CuSO4 per liter. Another question, 10% of sulphuric acid mean add 100 ml sulphuric acid to 1 liter of water, or water plus Sulphuric acid should be 1 liter? Thanks for your help

Плохо,что нету перевода - но слышно,что это профессионал своего дела.

What if I use salt instead of copper sulfate

We use both inches and cm's in the States...

To use a steel crucible, use steel not thin sheet stuff and spray a silicone spray as a release agent. I made a 5mm steel to make mine and the copper doesnt stick.

How to separate lead and tin from gold &Silver slimes which we get bottom of tub

This method is for separating copper from gold but not other metals, right?

How are you sir, these days you are making very few videos, I am very worried about one thing that in Stannous chloride test, which metal is the mark of dark Brown color, I don't understand

You could use the system to copper plate anything you want as part of the process.

In `MURICA we would use centimeters in this application and either use Celsius or a thermometer that references both Celsius and Fahrenheit. In 'MURICA 100 degrees F is referenceable along with 1 foot or 1 inch. IE if you said it was 85 degrees weather I could easily imagine that or a piece of wood was 2 inches wide or 4 feet long I could also imagine that. IF you said 50 degrees C or 20 centimeters in means nothing to me. Only 1 meter is referenceable since its similar to a yard and I can imagine the length or a yard stick. In this example no imagining is required and they're just number perimeters to be measured off. But I would probably convert over to Fahrenheit just out of curiosity to reference a similar temp. say hot enough to burn you. Hot enough to cook a brownie. Anything hot enough to glow red becomes unreferenceable beyond that threshold. Anything that's colder than waters freezing point in F. becomes unreferenceable. In conclusion we use both metric and standard and usually only use standard for quantifiable relationships. IE a foot is about the length of a foot. A yard = your arm. an inch the length between the first and second knuckle. Everything else seems to be based on quantificational relationships based on experience of use similarly to how someone would be able to relate the weight of 5 stones when I would have no idea of the weight of the original stone they where referencing unless I became familiar to the measurement system.

Dude is it just me or did I miss you mentioning at all how gold is a subject in all this as you go into great detail about getting copper on a cathode and also why this process of which the deposited outcome that mostly may seem to be a mess to someone not in the know would be useful?

i have 2 bars of non magnetic metal ( in cuboid shape) about 1.5 kgs each , this consist of 16% of gold, 1 % silver 83% copper (ie : after a test made by specialist)… what should i do if i want to extract the Gold ,.. does electrolysis could be proceed? If can how to do it ,… at this moment i have Cloric acid , Nitric acid, copper plate, carbon rod, copper sulfate (granular)… hope to hear ur best advise

Can we also recover silver from mlcc using this method? Plss reply

High five for the electrolysis fraction :-)

Copper sulfide is Cu2S Copper sulfate is CuSO4

+👍👍

pro-tip for mold creations....raw potato, easy to cut & holds up wonderfully under extreme heat.

i want to this kit .can u help me

I must have missed something because I’m 22:34 into this video, and I still don’t know where the gold comes in.

Hi sir, I am sridhar from india . We have more studded diamond jewellery product any one share how to remove the diamond from gold . Need electrolysis process

22:28

You seem to be under the impression that anything that isn't copper won't go into solution because it's copper sulfate. Only things that are insoluble (like the gold) in water/sulfuric acid will drop and become part of the slime. Anything that's soluble ends up in solution.

As jy flou swaelsuur opgooi sal dit die koper op los en behoort die goud boontoe te dryf. Flotasie effek sal dit aanhelp.

🍎🌹👌🤝

The idea is good but the setup you made is not very efficient

lol @ 'noisy cow'

Why don’t you just strip the gold off using a piece of gold for the cathode
