Thank you for sharing your experience, I would never even have tried that if you hadn't mentioned it!

By the way, the reason the copper isn’t malleable or ductile in that form despite being very pure is that the crystal structure is irregular. The malleability comes from the ability for atoms of pure copper to be arranged in a very organized way. The electrodeposition results in unorganized arrangements. You could organize the copper atoms by heating if you wanted to.

That's really cool. That probably helped alot. You can reuse instead of replace both the stainless steel and you can melt the copper into an ingot for whatever you'd use it for later. Have a GREAT Day!

In a professional refinery they usually have painted the edge of the stainless steel cathode so the copper doesn't catch on the corners.

Yeah, that would definitely make it much easier to remove the Cu, the edges are always the hardest part! I knew they sometimes used plastic clips to shield the edges, didn't even think about just using some paint to seal them.

Thanks for the comment Willy ! Always appreciate it!

sir, i need your guidance: => first of all i dissolved the copper ore in a sulphuric acid solution. => then i dissolved copper oxide ore in this solution. => once pregnant solution was prepared, i poured the pregnant solution in a separate tank. => now using stainless steel and electricity i did electro wining in order to deposit copper on anode plate. but the problem is: copper is not depositing in a "sheet" form!!!!! it is depositing like a copper powder. when i take out the anode plate from solution, it is nothing just a copper powder. but we need copper sheets !!!! plz guide how to get copper sheet through these processes???

On this KZread video you said thicker on both and loose copper. I think if you do a specific gravity test you’ll find the SG is less on top of liquid than the bottom. The copper liquid on top has lost some of its copper and the lower you go the higher copper content is greater. The loose particles of copper means voltage to high, lower voltage and increase amps. Like the video brother

Get a small, cheap diaphragm based aquarium pump and use it to circulate the solution to keep the copper concentration even throughout.P.S. You could even use those copper peel (once made) as new future starter plates instead of stainless, saving the trouble of needing to remove them

How do you build the copper cell

Test the ph. And keep it around 3. It will go down over time. Use some caustic soda to bring it up. Not use how long it will take but i asked one of the owners that i work for. The company use to make cathodes for the copper mining industry and he had a test cell .

Hi, thanks, will definitely look into it, this is interesting considering I've had some problems with my electrolyte on the final day of processing!

The reason why your bottoms are thicker than top parts is that electric charge is focused on the egdes of the plates, leading to higher electrolysis rate. I would imagine that side edges also got thicker copper coating.

@successfulengineer

5 жыл бұрын

100% Correct, side edges are definitely the thickest part. I guess that is where the current "hotspots" are, so that is where the copper deposits. The top is above the electrolyte, so no edge there.

Whate acid in uses

why would you not use copper sheet for the anodes instead of s.s. so you don't need to peel the copper off??

WhAt happens if you run like a car battery at 12 v

Excellent! Personally if I were going to use this regularly I would use copper for the cathode. When the process/cycle is done just put the cathode in the foundry and recast it. You may have to cut it to fit the crucible but a lot less work in total. The peelings would be good to make cement silver, etc.

Yeah, I considered using Copper cathodes, the main concern I had was brittle Copper dropping off and falling into the slimes. This happened a bit on my first experiment cell with Copper cathode. Those Copper skins are going to be great to re-melt for cement bars, they are very pure and I can easily cut them with some tin snips to fit the crucible!

@@successfulengineer Copper Cathodes, like this process, is one way to mine copper out of copper ore. Put in thin gauge seed sheets and extract thick gauge sheets of 99% pure copper suitable for electrical uses, since the weight and gauge has increased, it's added value. Putting it through a foundry and peeling copper sheet is just added steps to get to worked copper,or gold, if you can avoid peeling, if what you're looking for is free copper sheet. The copper sheets need to head straight to a hot rolling mill, any steps of foundry work or peeling are inefficient for sheet copper production. I guess this copper cathode stock is also melted down for producing other things like rod,pipe or bronze/brass castings, So your current process is not entirely out of step with efficiency of industry. Unless the plan is scrapping it, the peeling is still an inefficiency if you can avoid it.

If I understand, you are doing electrowinning of impure copper in CuSO4 solution. Black slime contains Au,Ag,.. metals? What voltage / current you use for electrowinning?

Hi Kristian, I'm not 100% sure that this processing is electrowinning, I associate electrowinning more with recovering metals from a solution. You are correct though, the black slime contains all the non-Copper metals. I controlled the current for this procedure, you want approximately 20mA per square centimeter, the voltage across the anode and cathode ends up being around 0.3V. I think I show this somewhere in part 1 of the video.

Nice work. I was looking to do this when I get my setup going. Im guessing that the bottoms are getting a thicker layer as there is a fair chance of the plates being closer to one another as they can pivot. You may also want to consider using it to remove tin and silver - low concentration nitric acid cell.

Hi Luis, 4A is much too high current! That is most probably the reason why your Cathode Copper is brittle. With 20cm2 you want to use maximum of 400mA (0.4A) current. 20mA per 1cm2. Also put a air bubbler in the bottom to make sure the solution is moved around, that also helps to get a nice even deposit.

Hi David, thanks for your nice comments! To get a smoother coating on the cathode, the two things that I found makes the biggest difference -> 1. Make sure you limit the current to around 20mA per square centimeter, you can even make it lower like 10mA per cm^2. 2. The solution must be moving around, I added an air bubbler to move the solution around, but you could also use a pump.

Find a cheap solar-panel, charge controller and battery. Let the sun do the work for you during the day as well as charge the battery; the battery continues the job until the sun comes up again.

You could bag your anodes. That way you dont have issue with filtering just incinerate the bags, hcl incinerate then nitric acid. Also your number of cathodes should be one more than anodes. Keep the temp around 60 degree f.

There is no Tin in these particular pins, so I have been having good luck with just letting the slimes settle, then dry, incinerate, then straight to Nitric to leach the Silver (dropped as Silver Chloride) and Copper. Then wash out the excess Copper Nitrate and go straight to AR. Have been getting a great yield. The only real downside is that something builds up over time in my electrolyte, I suspect Nickel, but not really any good way that I know of to test. It basically means that I have to change out my electrolyte for every 3kgs or so of Anodes.
