Modern computer chips manufactured after 1998 have very little gold content in them because most CPU's no longer use solid gold wire bonding technology or gold-plated lids in their packaging. For the purpose of scrap gold refining, these processors typically have the lowest gold content in them of all the processor type packages.
To recover gold in the laboratory experiment, the team salvaged the electronic motherboards from 20 old computer motherboards and extracted the metal parts. They dissolved these parts in an acid bath so as to ionize the metals. How the gold is recovered: Gold ions adhere to a sponge of protein fibrils.
However, with the right knowledge, experience and tools, you can remove valuable gold from computer parts, other discarded electronics. Things You Will Need: Scrap electronics
For gold flakes recovery, use a solution of hydrogen peroxide and muratic acid to dissolve the adhesive on computer parts, then process with sodium bisulfate for gold precipitation. Employ aqua …
In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straight-forward and pretty easy, but the …
Recovering gold from junk electronics, also called urban mining, may be profitable if you can amass large volumes of electronic waste (e-waste), particularly computer parts. It may not be worth the …
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 …
- In this video, the content creator demonstrates the process of recovering gold from printed circuit boards (PCBs) found in scrap computer parts. - The process involves three major steps: separating the gold from the circuit boards, purifying the gold, and precipitating the gold from a solution. -
Collect your scraps. In phones, most of the gold is in the SIM card, the main board and the smaller components on the back of the LCD screen. Use a magnet to separate all gold-plated steel parts ...
Electronics are chock-full of gold, but getting it out is so difficult that most of it goes to waste.A New Zealand startup has found a way to extract gold from old circuit boards using inexpensive chemicals …
Recovery of precious metals from computer scrap is a highly specialized process that involves disassembly of the computer, separation of precious-metal-bearing components and a series of chemical processes to …
Removing the Gold Gold can be removed from circuit boards in a variety of ways. It can be scraped off of the boards by hand, which is time consuming, but yields excellent results. The gold can also be removed via a process known as reverse electroplating, where a chemical solution and electricity are used to draw the gold off of …
Use a piece of metal with a gold plating on it to attract off the gold from the PCBs fingers and such. xs400 September 7, 2016 05:58 AM How about some genetically modified bacteria?
The Canadian researchers' alternative is a solution of acetic acid and an oxidant — a nontoxic technique to dissolve gold, which is stripped from circuits in about 10 seconds, leaving intact copper, nickel, …
Should I start off with a salt and vinegar solution to seperate the gold from the computer parts (as I will need a few liters to cover all the scrap I have) and then …
Recovering gold from junk electronics, also called urban mining, may be profitable if you can amass large volumes of electronic waste (e-waste), particularly computer parts. It may not be worth the ordeal to extract gold from a small pile of junk hardware. It's best to find good sources of free e-waste for maximum profits.
Here at Manhattan Gold & Silver, we don't recycle gold from computer parts. Our lots are typically fewer minutes in nature and include metal scraps used in dentistry, jewelry, pawn and other industries. Still, it's fascinating to think about all the unique and interesting uses manufactures have developed for gold.
Mix a refining solution. Although you have recovered the gold from the electronics scrap, it may not be pure gold. It may be 12k or 18k gold, so now we will refine it to be pure 24k fine gold. Take a second beaker and pour it half full of Aqua Regina. Be very careful.
heh. When I first started my search into refining, I found a pdf someone had wrote entitled "Refining Gold In Your Basement for Profit". They recommended "sitting a small fan in the doorway to circulate some air", and warned "when using a propane torch, do not lay your torch on the floor, as propane is heavier than air and can settle if you …
I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. There are many tutorials that claim to offer methods of gold recovery such as …
The researchers extracted the metal parts from 20 old computer motherboards and dissolved them in an acid bath to ionize the metals or separate them into positive and negative ions.
Hello, I am new here, just trying to find any contacts in Calgary, AB, Canada regarding Gold Recovery From Computer Parts. I have access to lots of Computer Parts, was thinking to recover gold from them, but it seems pretty difficult to me, at least for now while still learning about this industry, so selling most parts on Ebay and local facebook …

We buy gold from nearly any source ranging from old jewlery and gold coins, to electronic and computer scrap, to gold plated pins and connectors. We refine …
The quantities of gold you are looking at with consumer electonics are small. You will be working for grams not ounces, unless you have some huge operation with a steady flow of material. Some of the parts (cpu's and memory) sell very well on ebay. If refining is your interest, you will find everyhing you need to get started on this site.
If your gold is unrefined, your best option may be to ship it to a refiner. These processes may be challenging and cost-prohibitive for you. Another issue is that if you try to refine your own scrap, you may only recover the gold and not the other precious metals that may be present, such as silver and platinum.
Hello there everybody. I am starting to be conscious on gold from computer parts like video cards and ram chips. Is there gold on those like the connector... Forums. New posts Search forums.

Sounds almost impossible, from three boards even old server boards,even if they were from 1996 & had pentium pro processors, the gold standard of 1 gm each,being they don't have more than 4-5 ...
My 1st attempt at gold recovery stopped in its tracks. I took a friends advice and tried 2 parts Muratic acid and 1 part Hydrogen Peroxide to extract gold from pc boards and cell phones. He has since went missing and I dont know what the remainder of this process is. I'm a single father so a cheap process is what I need.
Used electronics and electronics scrap can be excellent sources of Gold, Silver and Palladium. These metals are used because they each have certain qualities that improve performance of electronics like computers, including excellent electrical conductivity, thermal conductivity, and resistance to corrosion.
For profitable gold extraction from computer parts, focus on older electronics and server boards due to their higher gold content, and use the chemical extraction method mixing 2:1 hydrochloric acid and 3% hydrogen peroxide, soaking circuit boards for 7 days while stirring daily for efficient gold recovery.
