  • would this work with chloroauric acid?

  • @LongBean420 It wouldn't. You would probably end up dissolving all metals including the electrodes if you used chloroauric acid.

  • can you add to the description what concentration of H2SO4 and the electrodes and voltage and amperes please

  • So when I went to a low end jeweler to get my necklace polished and he told me it wasn't really gold, this is what he did behind that door, he stole my gold!?

  • whats the point of this?

  • @mcrfuse To recover gold from gold plated objects.

  • @metalicmario Ya we know that but is the pay off or finished product worth any value?

  • @782Matty Of course. Gold is very valuable.

  • Please read previous comments to answer your questions.

  • Went to lasersteve's website listed on the vid end...was curious about the electrolyte, anode and cathode he used to do this reverse plate...I didn't see it mentioned anywhere. The anode looks like copper, but is he just direct plating gold onto the cathode? Was considering this for a means to remove plate for further refining, but a soft-metal cathode won't withstand an induction furnace.

  • What voltage is being used? Is the gold in solution or stuck to the cathode?

  • @TheJayhaich Please read previous comments to answer your questions.

  • Looks like piss.

  • It would be about 2 million times more profitable to just sell the jewelry at half price or something. If you want to strip something, strip old cell phones, or discarded microchips. Those are all gold plated.

  • @ArtypNk Do you have any figures? Exactly how much is 2 million times more? What is this lot's true value? How much gold is on cell phones or microchips? How much reverse electroplating have you done. How much cell phone and microchip processing have you done? What is the cost of processing plated jewelry vs cell phones and microchips? What if I wanted to harvest this gold to make jewelry? Then what is it's worth?

  • How much gold did you get from the 200g?

  • what do you use to hold the gold

  • But i thought acid would dissolve any metals?

  • All the information you need can be found on the site given at the end of the video and the goldrefiningforum.

  • I just started reverse electroplating, and I am curious to know if you know the proper setup using volts, watts and/or amps for various power sources. And if you increase the power, will it speed up the processing speed?

  • Thank you. This will be far more cost effective and faster than distilling my own nitric acid to dissolve base metals. Less hazardous too. Cheers!

  • Im curious as i have a cell set up as well. What are you using as your anode here? ive tried various basket designs using either stainless steel or copper mesh but im tryin to find somethign less contaminating, or maybe a little more efficiant. Just tryin to get some ideas. Also, by chance what amp are you running here? i use a 10 amp but i was told you can go up to but should not pass 50 amps. Any input?

  • @socorban The anode in this video is copper mesh. Copper is probably your best bet. Its the cheapest and easiest to optain. It also has the second highest conductivity after silver. Silver however will break down as the acid gets diluted. Making a solid gold fine mesh would be very challenging and expensive. Copper is actually quite resistant to concentrated H2SO4. Most of your contamination will come from the nickel and steel in the scrap. Making a totally resistant anode is fairly pointless.

  • @metalicmario @metalicmario In that case ill just stick with the sheets of copper screen i have. A friend was talking to me about using graphite but i never touched it before and had no desire to fiddle with it either. Can i ask what your do for smelting> i have a crude set up, accetaline torch, ash couples and i use a nitrate and borax mixture but i can never seem to get the purity past about 87 to 90 "ish % without other chemical means.

  • @socorban Lose the term smelting. Its reserved for separating metals from ores. We are melting. I melt my metals with either a MAPP gas torch or oxy-acetylene rig. I melt them in crucibles of various sizes like seen in my videos. You need only use borax. Nitrates are a crude way to try and get slightly high purity by oxidizing base metals. Since you are only using acetylene it will not work anyway. The cell is only for recovery. In order to get high purity you will have to refine the yeild.

  • how do you get the gold out after its deplated?

  • @grated1000 There is a process but the simple answer is filtration. You can go on the website shown at the end of the video for more details.

  • could this process be used on computer cpu's and memory sticks?

  • @Airsoftkid212 yeah but lol would barely get any gold...

  • @Hyzing gold is gold is gold.. lol

  • @Airsoftkid212 well electro plating machine is expensive and computer memory and shit is hard to fidn so by the 1 month it takes u to get like 50 dollars worth of gold i dont think its worth it

  • @Hyzing This is not an eletroplating machine. This is a reverse electroplating machine that can be made for $25-$100. The amount of gold you accumulate depends on how ambitious you are. 50 dollars worth of gold at this momemt is less than a gram of gold. About a half pound of gold fingers or several cpus. Not a big amount at all although you wouldn't use a cell to process that kind of scrap. If you go to the forum or the site at the end of this video you should research "AP process".

  • What is the anode made of.

  • @Shavenhamster Lead.

  • @metalicmario is that the sheet onto which all the neck-chains have been placed?

  • @1Orrin From the order of the comments I think you are asking if the sheet where the chains are placed is made of lead. The "sheet" is actually copper mesh. It is the anode. The bar on the other side is lead. The cathode.

  • is that black sludge aqua regia?

  • @sh7de its gold

  • @metalicmario How many grams did you salvage from this process?

  • How many grams did you salvage from this process?

  • @SlowinTheMotion I couldn't tell you. There was much more scrap processed in this cell after this video was shot.

  • Where's the picture of all the gold?

  • @Grundalizer The gold settles at the bottom of the cell as a black sludge. Nothing spectacular to see. Picture the gold powder in my melting video and then picture it being black and slimey.

  • Does this work with silver plated obiects to?Thanks

  • @borostmcbarna I believe someone on the forum has a silver cell working. They get it to work using a different concentration of sulphuric acid. In doing so other things have to be accounted for from this type of cell. Go to the forum and search for silver reverse plating cell.

  • I want to do make an electrolytic cell, and i want to know if the gold deposits on the bottom or on the anode or cathode, and which one is the anode and which is the cathode. And is the bath consisting solely of sulphuric acid or is there something else in it?? Pls help me out.

  • @KodaB1 Go to the website given at the end of the video. You can watch videos there and learn everything you need to know. You can also buy all the materials you will need.

  • @metalicmario tyvms, will do that.

  • Cool Mario...

    didn't saw that one... nicely done !

  • How do You know other metals (those from under the gold) are not undergoing the process as well? 

  • @Phacias

    You can't tell. In fact, you should assume that contaminant metals are coming off with the gold. This happens in very small amounts however. Each item depending on the type of underlying base metal, how long the material stays in the cell and temperature will determine how much contaminant comes off of the scrap. An electrolytic cell is for gold recovery and not refining. You must understand the difference between the two when getting into refining precious metals.

  • @metalicmario I have a couple of scraps that are unmarked, and I'm not sure whether they're solid, filled or plated. I'm still waiting for my testing kit, though, but I assume this method will not work for sub-24k solid and filled? Are there any other way to refine sub-24k to pure powder form?

  • @sh7de Actually... The cell is made for plated scrap only. It can be used on gold filled but with limited efficiency. I've never been able to fully recover gold off of gold filled items using the cell. Gold filled items are made of a thin layer of karated gold mechanically bonded to a base metal. Much thicker than plated items. So I bet you can already guess that it won't work on karated ("solid") gold.

  • @Phacias If the copper basket in the video was being attacked to any significant degree than the bubbles would probably be brownish.

  • were do u buy the sulfuric acid from what store

  • @ejmiss123 True Value. You can also fiind concentrated H2S04 at Ace Hardware. I've never seen H2S04 at Lowe's or Home Depot.

  • @metalicmario McLendon's apparently carries somewhat concentrated (70%?) as drain cleaner.

  • @elementcollector1 I'm not familiar with McLendon's. The sulphuric acid used in the video is Rooto professional drain opener and is about 93% pure. 70% will not work as lower concentrations will also attack copper.

  • @metalicmario I see. And copper was what you used for the electrodes?

  • @elementcollector1 The anode is lead and the cathode is copper wire mesh. Go to the website at the end of the video and watch the detailed videos. They are free.

  • How do you get the gold back out of the solution.

  • @MrJohnnipper Basically you'll filter the sulphuric acid leaving behind the gold (black powder). The H2SO4 concnetration has to be lowered with water before filtration. This is a dangerous process and has to be handled with caution as concentrated H2SO4 is a very nasty acid. Worse than HCL and HNO3 in my opinion. Go to the website mentioned on my vid to see how to recover the gold. There is another way to do it but you should try it this way first to understand the why not just the how.

  • Great VID, how much Voltage and Amperage  you use ?

  • @Kalf9999

    I use a standard 120V 2/10 amp battery charger. Its important that you use a manual charger as the automatic ones wont work. You can get one on the website at the end of the vid or pic one up most anywhere they battery chargers are sold. 2 amps deplates slower than 10 amps but 10 amps will heat up faster.

  • what's the anode and cathode made out of

  • @imatelly The cathode is made of lead. I'm not 100% sure about what the anode is made of. Looks like some grade of steel(not stainless). Most anything will work for the anode as long as it conducts electricity well. The cathode however has to be highly impervious to sulphuric acid which is why lead is used.

  • @metalicmario ty very much
