Collect all gold plated pins that you want to remove gold from. These pins can be found on the motherboard, cell phones and this kind of electronic devices. With this method you can also remove gold from plated jewelry.
Before you start the recycling process make sure that there is not so much other materials which does not contains gold at all. If you want to dissolve gold from pins make sure that you remove parts from these pins which are not gold plated. Also if there are CPU’s with gold on them make sure to remove ceramic parts or other materials for better efficiency in reverse electroplating process.
Because in this process you must use acids it is important to take safety precautions. Make sure that you have rubber gloves and if it is possible wear goggles or a face shield.
For reverse electroplating it is necessary to use chemical solution. This chemical solution servers as a bath that helps in gold dissolving process. Best known chemical bath for reverse electroplating is a mixture of three different acids with ratio 70-15-15 percent of each. Take this ratio in this order together with acids sodium cyanide (NaCN), sodium hydroxide (NaOH) and sodium meta nitro benzene sulphonate (C6H4NO5SNa). Pour these chemicals into a glass dish and stir them together with a glass wand.
This method of dissolving gold requires power source. Best solution for power source is to use car battery charger. Make sure to have alligator clips on the end of the both wires, the positive and negative one.
Connect negative wire to some stainless steel piece which will be cathode. Just plunge cathode into the solution and connect it with negative terminal from battery charger.
Positive wire leading represents anode and it must be connected to the gold plated items. You can make a copper dish in which you can put all gold plated items to make good connection for electric current flow. Plunge these gold plated items with anode into the solution and connect it with positive terminal from battery charger.
After you have done all these things take the power ON and wait for the electrochemical process to carry out. The gold will receive a positive charge and it will be dissolved by the electrolyte solution in the bath. www.cusabio.com il-6 elisa kit
Reverse electroplating process has a opposite way for attraction and the gold will move from plated materials to the cathode which is made by stainless steel. When this process comes to the end take the power source OFF and remove cathode from the bath. Let the cathode dry and peel of the gold layer. Gold can be peeled off of the stainless steel with easy and collected aside. When you collect enough of gold pieces you can melt them into one gold button or gold bullion and sell it.

GD from chennai we can find , the coated gold behind the copper cover plate over processors of cpu reacting them with 2hcl +1h2o2 is more long huge copper dissolving of plate . any other process say reverse plating give an suggestion .90% h2s04 electrolyte not suggested un avail

Well, I hope that ,Despite the Negative Comments Given to You, Forge Ahead ! There are many reasons why people Are eager to give you Advice like I see here. Now, You won't get rich on just pins and fingers. But don't let anyone tell you it isn't worth it. And ,by the way, Sometimes it's not the Pin itself, It is the Manufacturer. The Best Boards ever made were made by IBM and Ross Perrot "May he Rest in Peace" Back in the 80s IBM made the Most Expensive "Business" Machines. And the reason that Fortune 500 Companies Bought so Many? Gold! and Lots of it. I always Toss My IBM's to the side for Stripping. And to be honest I have like 20 of them. Now that don't sound like much, But if You knew How much Gold and Pt. Based metals are in one Board, You would see why that doesn't really Matter! Be careful of what You believe. Even I could be pulling Your Chain, (but I'm not) so I suggest that You actually BUY Your Own Copy Of Hokes Works. From a Bookstore, Not a CD or Disk because Those Formats are often edited for Space. And Also Printed Pages are edited as well. You will pay more, But 1.) you will be purchasing Real Hoke Information. 2.) You will sleep better knowing that someones Intellectual Property hasn't been Compromised.
You will know right away if you have a Real IBM once You have handled a Few. They are HEAVY! they weigh at least 7.5 pounds and up. And you will also know the value in one of those old babies, And why they costed more than $25,000 each back then. So, keep on going. Don't give up because of the Nay-Sayers that always respond to Questions like Yours. Like: Don't do it ,You Could Burn up and Die? Well that could happen if You let my Wife come over and Make your Breakfast! LOL Just use common sense, Write down the Order in which you will use to recover Your Prime Metals. Just Remember ,it is in those that leave you with Negative info,best interest's. Many of those sell products themselves, or Bootlegged Copyright. I just love it when they catch one of those "Thieves" and that is exactly what they are. They Sell ideas that aren't their's. In fact, I would be surprised if they have EVER had an Original Thought of their own! And Electronics are not Your only Choice. Buy a Good Fisher "Goldmaster 1000 Metal Detector. They cost around $800.00 bucks but they are addictive, You get You and the Dog(or Wife) off the Couch and Finding Real Gold ! Good Luck!

There is very little gold plated onto objects - I guess your talking about printed circuit boards and similar electronic equipment.

You need a LOT to make anything from this process.

You'll be very lucky to get more than a couple of grammes from 200 pounds of stuff. Recovery has to be done on the tonnes scale to be worthwhile.

Also, you can't reverse plate unless you have a circuit through the plating - are you going to wire every single piece up ?

strip the green solder mask and use a copper mesh to contact all surfaces

Answer 6 years ago

The solder mask is often epoxy based, how do you remove that ? The copper would have to be a.) Spotlessly clean and b.) not attacked by the same process.
Much of the "gold" you are recovering is inside the chips, as the bond outs from the chip to the legs, so you have to smash all them up too.

Once you strip the gold how do you plan to retrieve it from the solution?

Answer 6 years ago

when done right the gold ends up on a ss rod and peels off.
reverse electroplating is a misnomer its more "transelectroplating"
moving the gold from one object to another.
