He said it took him 3 weeks to scrape that much off the boards, with a planner, that's how difficult it is. There was a post on this forum, several actually, that talked about how to remove the finger boards from the board
Computers and other electronic devices contain gold and other precious metals in their circuit boards. As consumers upgrade their electronic gadgets, the precious metals remain trapped in piles of waste. There’s about 0.2 grams (0.007 ounces) of gold in a typical mobile phone handset. Recovery of this gold
Gold Recovery: Wait don’t throw those old electronics in the garbage, there’s gold in them there things. How about putting it in your pockets instead of someone else’s pocket? Laptops, phones, cameras, and the like are filled with gold plated circuit boards eve...
Back in the 70's I extracted the gold, copper and solder from from about a 100Kg of salvaged circuit boards. Even with the thicker gold used in those days I didn't get enough total return to cover the total cost of the processing. As I recall we got more return from the copper and other scrap metals than we did from the gold, still not nearly
Cut all of the gold-plated components out of the electronics. You do not want to waste your time treating the entire motherboard of a computer when all of the gold is plated on the connector pins, processors and or chips. Cut all of the gold-plated components off the circuit boards. Do not throw the boards away though, because there is still
Scrap Circuit Boards > Gold Fingers How to Recover Gold from Electronic Scrap Gold Fingers How to Recover Gold from Electronic Scrap. Details Written by Gold-N-Scrap. If you recall, when scrapping computers and other electronic equipment, we encounter a lot of peripheral cards which has Gold plated male slot contacts, i.e. the “fingers”. See picture below. (WARNING: The process
How to Extract Gold from Computer Circuit Boards? A discussion started in 2000 but continuing through 2019. 2000. Q. I have access to over 4 tons of old Computer Circuit Boards. I am wondering if anyone knows of a way that the gold can be extracted from these. I have heard that there is a solution you can soak the boards in and the gold will
A single circuit board cannot get you much gold but, if you have number of circuit boards then your chances of getting gold increases. While extracting the gold the right tool must be used. The circuit should be removed carefully and placed in a clean place before extracting the gold. The steps to be followed are as follows. The tools that are
Extracting gold from a printed circuit board is definitely possible but the amount of the gold in the PCB has to be evaluated first. The process involves a number of steps which have to be carried out carefully in order to get the desired results. There are some instruments and acids involved in the process. Necessary precautions must be taken before starting the procedure.
WAY more trouble, and WAY more of a risk than the tiny amount of gold present. The other materials present, especially on circuit boards and computer parts pose such a risk to your health, and the environment, nobody should be messing with them (except maybe in the case of major laboratory gold recovery setups that specialize in gold plating
Nitric process or CN process can be used to remove gold from gold plated/polished pins and connectors. From CPUs we can recover gold through aqua regia. Pyrolysis and hydrometallurgy are used for gold recovery from computer chips. Our methods of gold recovery from computer parts are 100% safe and environment friendly. They are quite economical
I have a lot of electronic and computer pins and contacts that are gold plated I want to remove the gold from. Is there a low cost stone or something I can buy to remove the plating so I can melt it into bars? I have tried some circuit board stripping solution called CBX from Shor International but it's very expensive, and it don't work on
29/04/2013· Today I was preparing my High Grade circuit boards by cutting and chipping away the parts that is not gold platted but to my surprise, many of the gold is hidden underneath the paint. Does anyone have any suggestions how to remove the green paint from the circuit boards?
How Gold Recovery From IC Chips Remove from the electronic circuit board. These ic chip samples are industrial waste. I have shown an example of removing the ic chip from the electronic circuit board. I collected the ic chip from various electronics circuits 1 kilogram Today I will recover all gold from ic chip. I use 2 liters of sulfuric acid boiled with 1 kilogram of ic chip Use at a
2006. This has been said a few times in this thread, but I'm sure it can't be said enough. All of you who are trying to extract gold from modern day electronics (IC sockets, edge connectors, monster cable, etc.) are wasting your time. 1 OZ gold = ~ 500$ You'd need about 50 computer mother boards to extract 1 oz of gold.
27/10/2010· Most circuit boards contain all sort of precious metals: Gold, Silver, Palladium and sometimes Platinum. All circuit boards contain base metals: Copper, Nickel, Aluminum, Zinc, Tin, Lead and Iron. As well, small amount of hazardous elements like Beryllium, Barium and others that has to be considered while processing scrap circuit boards.
"Gold Recovery for Dummies?" A discussion started in 2005 but continuing through 2019. 2005. Q. Well Hello. I just stumbled across this forum as I was looking for information on Gold Scrap Recovery and thought it was as good a place as any to start. I have read the posts and have to say that I agree with the many warnings associated with the
You do not have to be an electronics engineer to remove and replace bad parts. Parts that commonly need to be replaced include capacitors, transistors and various electronic chips. If, through visual inspection or through circuit analysis, you can identify which part is defective, you can usually repair a circuit board.
