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

In copper refining you can only use sulfuric acid. If you refine using AP (hydrochloric acid and hydrogen peroxide) you would still need to convert AP solution to copper sulfate by distillation driving off the hydrochloric acid and collecting it to reuse. NurdRage has a video out on this process. You can see it here. kzread.info/dash/bejne/eJ550bSilNnNiag.html According to the "reactivity series of metals" any metal less reactive (below copper on reactivity series chart) than copper will fall out of solution as black "slime". These are your "precious metals." those metals will be silver, gold, platinum, palladium, rhodium, ect. Those metals can be refined further using different techniques later on. I know this may seem lengthy but hope this helps to get a better understanding of process. 😊

Iron is not really an issue, it will not melt and end up in the anodes, and you really want to separate iron based pins out early. Obviously using pins with a Copper base is ideal. There is almost always Nickel present, which does not seem to cause big problems, it does contaminate your electrolyte over time which can be a pain. Zinc and Tin are also pretty common for brass and bronze pins, in that case, they end up in the slimes with the Gold.

Dissolving big bars of Cu with acids is never a good idea, it creates a LOT of waste that is very toxic. The electrolysis method works great, but I think in your case the Copper has too much other metals, you really want your Cu to be about 95% before the electrolysis process for best results.

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.

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.

Yeah, you hit the nail on the head, for those in the know, separating Copper from precious metals is a very hard thing to do. You either have to do it with wet chemistry (lots of toxic waste) or you have to use this kind of process. The vast majority of home Gold-recovery guys use wet chemistry and end up with buckets and drums full of toxic waste. This system gives you nice pure Copper (to sell or use) + all the other metals that also contain all the precious metals (the black goop)

@@successfulengineer I understand. This very fact as well as what the pros are of following the steps/procedures that you do, are not really becoming very clear in your video though, it could have done with some explaining. Tx anyway for responding!

Did you watch part 2?

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

Die elektroliet wat ek daar gebruik is basies flou swaelsuur, so eks redelik seker dit los nie Koper op nie. Die swart Goud slym is ook redelik swaar, so nie rerig enige manier om dit in die water te laat dryf nie. Wanneer ek die Goud slym uitgedroog het gebruik ek Saltersuur om die oorblywende Koper op te los, werk mooi en vinning.

@@successfulengineer Hello i got an question when do i see the solutin is over satuarted with metals lower than zero electronegativity like tin iron and co ? my ampere is dropping alot recently could it be that the solution it over saturated?

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.

Oh, not at all, I know that its actually the things going into solution that caused / causes me some problems. I think the main culprit here from memory was the Nickel fouling the solution.

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

I guess you could strip the Gold off the initial pins, you don't even need a Gold cathode if you use a Sulfuric cell, but this was more done out of interest than purely for the Gold recovery. I was interested at the time to compare the amount of hazardous waste created by the different processes.

lol @ 'noisy cow'

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

No efficient in terms of how fast it recovers Gold from the anodes, or not efficient because it uses a few cents in electricity per day ?

@@successfulengineer No criticism, just a consideration. Using a computer power supply and light bulbs to regulate the current certainly works, but you can do better. High current and low voltage adapter like a led strip power supply is more suitable, after that you can use the chinese module to step down the voltage and increase the current but I suggest to add an analog ammeter so you can check continuously the conditions of the cell (i saw that the change in size of anode and cathode tends to increase/decrease the overral resistance, but you noticed it too in the 2nd video). Your voltage was good anyway, the range 0.2 - 0.3 V allows to recover almost pure copper while all other metals remain in solution or, in your case, fall at the bottom. I hope to see more videos about this in the future ;)

@@Icchy92 Hey mate, thanks for the comment. Yeah, This is going back a bit now, but I think initially I tried to use some switchmode CV-CC power supplies, but they always had stability issues when trying to regulate down to 0.3V ish. I also used my lab supply for a while, but that was linear, so probably similar power wastage to the light bulbs! I think in the end the light bulbs and PC supply worked well because they were cheap and I didn't care if acid vapors destroyed them. The Sulfuric was not too bad, but everything in the area still corrodes super fast! All up though, it was one of the better ways I explored for recovering Gold, anything that avoids tons of acid waste is awesome! I have cast a few trinkets with the recovered Copper too, which was nice :)
