How to Recycle Gold from CPU Scrap: What You Need to Know

 Recycling gold from computer CPUs (central processing units) is not a new concept, and there are many different methods of doing so. The most common method is to use a process called cyanide leaching, which involves using a chemical solvent to dissolve the gold and other precious metals from the CPU. Here are the steps you need to follow to recycle gold from CPU scrap:

First, you will need to remove the CPU from the computer. This can typically be done by unscrewing a few screws and lifting the CPU out of its socket.

Once you have removed the CPU, you will need to carefully dismantle it to separate the different components. This can be done using a pair of pliers or a screwdriver, depending on the specific design of the CPU.

Once you have separated the different components, you will need to carefully remove the gold-plated connectors and pins from the CPU. These connectors and pins are usually made of a gold alloy and can be recovered by breaking them off and melting them down.

After you have removed all of the gold-plated connectors and pins, you will need to grind the remaining CPU into a fine powder using a hammer or other crushing device.

Next, you will need to use a chemical solvent to dissolve the gold from the CPU. The most commonly used solvent for this process is cyanide, which is highly toxic and must be handled with caution. Other options include aqua regia (a mixture of hydrochloric acid and nitric acid) or smelting with a flux (a substance that helps to purify the metal during the melting process).

After the gold has been dissolved, you will need to use a process called electroplating to recover the gold. This involves running an electric current through the dissolved gold solution, which causes the gold to be deposited onto a cathode (a negatively charged electrode).

Once the gold has been recovered, you can sell it to a scrap metal dealer or refinery, which will pay you based on the weight and purity of the gold.

It is important to note that recycling gold from CPU scrap can be a complex and potentially dangerous process, and it is not recommended for inexperienced individuals. If you are not familiar with the process, it is best to leave it to the professionals.
