E-waste precious metal refining system is designed to refine and recover precious metals like gold, silver, palladium(Pd) and platinum(Pt) from electronic waste (e-waste) like circuit boards, including CPU, RAM, pins, and other computer components. E-waste is classified as hazardous material therefore should be managed properly. However, the …
Refining. The gold precipitate is further refined by melting/smelting processes to remove remaining impurities and extract pure gold metal. A few important notes: ... While possible, extracting gold from e-waste at home is generally not recommended due to safety risks. Industrial e-waste recycling facilities have proper equipment and controls ...
actually, the smaller the gold plated pieces, the more plated area you will have. theres more gold in a pound of gold plated pins than there would be in a pound of gold plated chain. gold filled is a totally different thing altogether. the larger the piece, the more base metal you will have to deal with. the smaller the piece, the more gold you ...
Au plays an important role in modern microelectronics 5; indeed, the Au content in electronic waste (e-waste) is estimated to be up to 80 times higher than that in the world's …

Hello to all the group members While smelting e-waste has been discussed multiple times, we are facing some situations for which we are seeking solutions. From reading the threads, I know a few solutions but would really appreciate help from the experienced smelters. 1) We are using a 2 m3 Top...
Hello everyone, I am part of a startup that is venturing into the world of precious metal recovery from electronic waste. We understand that this is a complex and delicate process, and we are keen on doing it right. We are currently seeking advice and guidance from experienced professionals in this field.
Dealing with waste, and safety to begin with, you need to understand the basic principles and how to do them safely, Hokes book, which does not deal with electronic scrap, but deals with any problem with recovery and refining gold (including the problems with electronic scrap). Testing for gold in solution, also found in Hokes book, she also ...
The extraction of gold (Au) from electronic waste (e-waste) has both environmental impact and inherent value. Improper e-waste disposal poses environmental and health risks, …
Hello ALL, I have been a member of this great forum for years now and I got benefit of 100s of posts and learnt how to start extract and refine gold from e-scrap in small scale and I managed to make some profit out of this but still in small scale. Now, I have been asked by someone to search...
Researchers at University of Saskatchewan in Canada have found a cheap, fast, and environmentally-friendly way to extract gold from materials while producing re-usable waste — a technology that might have potential to …
The polymer, called COP-180, selectively captures gold after it has been leached from e-waste. Credit: Yeongran Hong. 122. One thing holding back e-waste recycling is the actual recycling process ...
The demand for gold recovery from E-Waste is significant due to its high value. Here, authors present a practical method for extracting gold from an actual E-waste leachate using alginate-derived ...
The Refining Company buys of any kind of E-Scrap, recovers the precious metals within and pays you the highest price. The Refining Company, Inc. Home. 1-888-700-5918 ext. 4. Home; Materials. Gold; ... We buy most any kind of E …

The E-waste solutions either need to be treated as hazardous liquid waste and taken to a proper disposal facility, OR if you can handle it, dehydrated into a …
That is the process for the most part with e-wasye recycling. You cherry pick the items you know have precious metals, and you remove the "burden" from the precious metals. As a head starter, don't waste money and time on green wafer chips... there is zero precious metals in them.... the manufacturer's way of doing the same thing for less money.

I figured it would be a good thing to start a second hobby doing E Waste to get the metals I needed to make the jewellery. I am using some pieces of like heat sink fins directly ...
PROJECT BACKGROUND. For most large e-scrap recyclers, the most common solution of precious metal recovery is selling e-scrap materials to one of the few large smelters in the world, and the smelters apply pyrometallurgical method (burning everything in furnace) to process these e-scraps and give the recyclers credits after many discounts and management fee charges.
yes, yes you can. And you don't have to know how to refine anything either. You can make a pretty good living if you just collect, take apart, and sell components of computers, etc. Sell the copper wire, the power supplies, the fingers, the CPU's, the expansion cards, the motherboards, the heat sinks, the HDD's the memory, and all the steel. Collect it up and pile it …
Thank you Sam and Geo for replies, I have a good feeling about this. I first wanted to see if there was a way to get rid of the base metals, and process the gold at the end, but as you pointed out, one method is: Solution of all base metals beside gold (HCl leach, dilute sulfuric leach, AP, dilute nitric), but this seems to use a lot of chemicals and producing a good amount …
Because of the lack of suitable recycling methods, he continued, more than 80 per cent of "e-waste" ends up in landfills, making it a pretty serious environmental issue. There are two current industry standards for removing gold from electronic scraps. The first is pyrometallurgy, which burns the gold off using high temperatures.
Worldwide mountain of waste electronic and electrical equipment (WEEE) will total an estimated 57.4 million tonnes. Last year's Global E-waste Monitor 2020 reported that an estimated 53.6 million metric tonnes (Mt) of WEEE was generated in 2019. That represented a 21% jump in the five years since 2014.
Jobs that are left for me will only last about a week or two. I'm looking at e-waste to add more jobs. I have read a lot already regarding e-waste processing. I'm looking at wastes that can be chemically processed without the need of pyrolysis, large …
Pulling gold out of e-waste suddenly becomes super-profitable. By Paul McClure. March 03, 2024. Using a food industry byproduct, researchers have extracted 22-karat gold from old motherboards ...
I belong to a gold refining forum, as I have a small recycling business. There are a lot of ways to get gold from components on a circuit board or from plated pins. There are ways to bleach or hydrogen peroxide to put metals into solution, but aqua regia is the fastest and most effective method.
The same gel used as a replacement for acitve carbon. Still need cyanide or some solvent for gold. It's supposed to be more selective for gold ions than others.
Most of the members on the forum that refine e scrap do so with cherry picked items with good or easy amounts of values to access, the main value in much e scrap is the base metals not the precious metals which is why much of the scrap ends up in copper refineries but they have hundreds of tons of materials to process with high copper content plus the e scrap …
Hello all, I've been letting my gold fingers sit in HCL with an air pump for a while now, about half of them are off. I recovered a first batch of them by switching buckets, rinsing with water and using a paper filter to catch the foils, it worked pretty well. The water I …
A record 53.6 million tonnes of electronic waste was generated worldwide in 2019, according to the UN's Global E-waste Monitor 2020. The raw materials in this e-waste were worth around $57 billion - with iron, copper, and …
Turn Your E-Waste To Gold. Congratulation on producing your first carat of gold! As you can see, the process is quite time-intensive, but if you are a fan of science experiments, this one is definitely worth it. In the end, you will need to use chemicals if you were to get at least some amount of gold from computer parts.
