Are you’re looking at opening a small yet profitable business that would start paying rich returns almost immediately? If yes, then I would suggest you try a business to extract gold from electronics and computer parts. As you would surely know, gold is a precious metal whose prices usually rise over a period of time.
Actually, recovering gold from computer parts isn’t a simple, home-based business. Nor should you even attempt doing so at home because it involves chemical processes. But if you can open a small workshop, it’s possible to extract gold from various computer parts and start making money.
Computer Parts with Gold
There’re quite a few computer parts that contain gold. I’ll list them for you. However, since these are different parts, you’ll also required different processes to recover gold.
Computer parts that contain gold include:
- Motherboard processors
- Hard drives
- CD & DVD drives
Additionally, computer parts also contain silver – which is another precious metal and of course, copper, which is commonly used for connectors and wiring.
As I mention earlier, since different parts of computers require different ways to recover gold, let’s see some of the processes you can use.
Extract Gold from Electronics & Computer Parts
Most of these processes are complex. Hence, you’ll need proper training to extract gold from computer parts. And of course, you’ll require a license too because it involves buying various chemicals that aren’t available off the shelves.
The most common way of recovering gold from computer parts is known as Gold Cyanidation. It’s also known as the CN process or the MacArthur-Forrest process. And since it involves the use of cyanide, a highly toxic chemical, the process can be done only at labs or workshops that have necessary permits and clearances from the government.
To extract gold with the CN process, you’ll first have to separate the metal items in a CPU, Motherboard and other computer parts that contain gold. Later, these scrap pieces have to be washed with a moderate strength acid solution to remove plastic, rubber, epoxy and composite.
When you have the metal part clean and exposed, follow the CN process at your workshop or lab. The gold comes in the form of an assay containing Potassium Cyanide. This assay has to be further purified using a mix of Nitric Acid, Hydrochloric Acid and Sulfuric Acid in the right proportions, to create a solution known as Aqua Regia.
Gold dissolves easily in Aqua Regia while the Potassium Cyanate assay separates swiftly. The process is a bit risky because it involves highly concentrated acids and cyanide fumes- both of which are potentially harmful to health, if you don’t take proper precautions.
Aqua Regia Process
It’s also possible to directly extract gold using the Aqua Regia process, provided you’re ready to settle for a little lesser quantity. The CN process allows you to recover up to 98 percent of the gold from computer parts.
In stark contrast, the Aqua Regia process enables you to recover between 90 percent and 95 percent of the gold only. The acid mixture reacts quickly with gold and causes a small drop in its volume.
Clean the computer parts with golds, remove all outer covering and drop the pieces into a glass trough containing Aqua Regia.
These parts and the metal alloys with gold dissolves in the mixture. Upon neutralizing Aqua Regia, you’ll find the gold residue along with those of other metals. The gold residue can be purified to extract 99.9 percent 24-Carat gold.
This isn’t exactly the way to recover gold. However, you can sell the char for a lot of money since it contains gold.
Remove all parts of a computer that contain gold and burn them in a large metal barrel. You’ll be able to recover only the charred pieces or chars from the ashes since they’re made of metal.
Usually, professional gold extractors will weigh the char volume, estimate the amount of gold and pay for completing half the process. However, they’ll buy the char only if it’s clean and free of residues of any other material. Hence, you may have to burn the pieces several times to get pure char.
Recovering Gold from Mobile Phones
The above processes are also useful to extract gold from mobile phones and other discarded electronics including remote controlled toys. However, the volume of gold in mobile phones will be much smaller than computers.
License to Extract Gold
Here it’s important to bear in mind that recovering gold from computer parts and mobile phones can be done only by qualified metallurgists and other professionals. This isn’t a business for the unqualified.
Before you enter the business, make sure you have proper licenses for operating a gold recovery business and possession of hazardous chemicals.
As you can see, there’s a lot of money in extracting gold from computer parts and electronics. However, this business is for qualified and experienced people only.
