. The amount of gold you will get from 4 tons of circuit boards may not be worth the effort and cost. There are at least two ways to get the gold: (1) cut off the tabs and strip them in cyanide (2) burn the entire collection, smelt the copper and gold out of the ash, then extract the gold from the copper. Both methods are highly regulated environmentally, as well as being dangerous. I suggest you stay out of the business.
+ Hello, those boards if made before 1990 should be worth a dollar per pound after you cut the gold plated material off. There are better ways of gold extraction other than cyanide. I have refined gold for many years and have never used any form of cyanide. Use a dilute Aqua-regia. Arnold H ++++++ I have managed to slice the gold/copper strips from the PCB eliminating the board process. I now have an average size pill bottle full of these shavings. Would it be in my best interest to now try separating the 2 or should I sell them outright not knowing what percentage of this plated scrap is gold. The boards are of 86-92 era. I also am very curious as to why these shavings are magnetic when neither gold or copper are magnetic. One answer I got was that since electrical current has flowed though them they now have a charge to them. This sounds logical to me or is it perhaps another alloy that I don't know about. I would really appreciate any light you can shine on these matters for me. D Marshland
Hi. My husband I have access to a large amount of really old circuit boards. We are not sure of the quickest and safest way to extract the gold from them? Here in Calgary, Alberta people will pay insane amounts for the gold. Marie S

Hi I have access to a lot of computer circuit boards brand new in fact. I want to know where can I recycle them. I heard that some people pay good money for them and I was just wondering if someone could give me their opinion on where to start even looking for a place to recycle them.

Hi, Marie, Heather, Matthew --
E-waste has become a curse on the planet. The first problem is that amateur recycling is a wrecking ball that scatters toxic waste everywhere. Add to it that the cost of recycling the whole item is so close to break even that the rest of the toxins become unrecoverable and buried everywhere if people do 'cherry picking' on the waste. The following video, and there are dozens like it from many major environmental organizations, explains why leaving the scrapped electronics whole is a pivotal ingredient in the world gaining control over the e-waste problem:
One convenient widget for locating green recyclers is on the Crutchfield site at http://www.crutchfield.com/environmental-policy/recycling.html.

Arnold H of Hamilton, Ohio: I've been thinking about putting
together a not for profit substance abuse recovery home and I'd like
to understand the ins and outs of breaking down to a component level,
home and business electronics and then selling them for
salvage.
Do I sell circuits boards one place. Batteries another, plastic in
yet another and of course our end goal is to provide some employment
and fund raising.
If this won't stand on it own? Are there government underwriting
funds available? Do you know of guide to such grants?
Thanks you,

Hi, Tod. There is a "green recycler's pledge", which is intended to make the recovery of e-waste part of a sustainable economy. So "green recyclers" are forbidden from using prison labor or slave labor because it is impossible for anyone to build a legitimate business that can compete against slave labor.
Similarly, grants force real businesses into failure by letting the politically-connected compete against them while having the public pay most of their bills. When the feeding trough runs dry, the real business has been shuttered, the grant mill moves to greener pastures, and the public is left with nothing but bills and shuttered businesses. So I suspect that grants are forbidden for green recyclers, but good luck.

I have some old and new computers and just wanted to know if the processor has more than the other parts.I think the older computers have more than the newer one's but which parts have the most maybe I will just go for that part and leave the rest alone. THANK YOU ALL FOR YOUR TIME, DENNIS

how is the last stage to recover after go through the process and end up with gold liquid and prevent it to become black during burning

Ok curious.... I read one on here that said wouldn't be worth the
time....
I broke down 5 comps.... I got 2 ounces of GOLD. from it... ok is the
GOLD not going for $1000 to $1200 per ounce now??

Hi, Chuck. I doubt that your gold is as pure as you think, because it sounds improbable that a computer would have $400 to $450 of gold in it and sell for $399 complete. Please let us know how big the check actually is after you get it! We sometimes see people posting glorious tales about how much gold they have recovered from scrap, only to find them selling scrap on ebay :-)
Good luck.

Well here goes i know it is very possible to profit off of old pc boards because the price of gold was a lot lower then say in the nineties gold may have been 600.00 hundred per ounce compared to now 975.00 per ounce so yes it can be profitable to dissect old boards for gold silver platinum and copper just be careful of health hazards i will be honest most people don't want you to know $$$$ in them there computers

This strikes me as ridiculous, Mark, but if you provide a reference I'd like to look at it.

I came across some electrical contacts from heavy duty connections and was told they were platinum or silver. They are soft enough to scratch and are harder than lead, I'm trying to find out if precious metals were used in high voltage connections.These pieces are about 50 yrs old, and I believe came from an old steel mill. Also the dime size pieces are quite heavy 4 of them weigh almost 1 ounce.Thank you...Any info would be helpful.

Hi, Jim. If they truly are dime sized (0.0207 in3) and four of them weigh 1 ounce, then their density is 12 oz per cubic inch, i.e., .75 pounds/in3, which is much heavier than silver or lead, a little heavier than gold, and about the weight of platinum.
For this to have any validity, though, you need to carefully measure that they are dime-sized, not eyeball it, and you need to weigh them, not guess. If they are as heavy as you say, they are worth taking to a jeweler or gold dealer to be checked, as only precious metals or tungsten would be this heavy.
Regards,

May 20, 2009 in reference to the platinum in computers. i.e hard drives. there is only a very thin layer of in located on the disks themselves and even the amount in that is based on the age of the hard drive. the process involved in recovering that involves a lye solution which can be EXTREMELY dangerous using if all safety precautions are not followed. robert godsey
July 21, 2009 Your circuit boards are worth Serious money if you have
"tons" of them. We buy sell and process many thousands of
pounds of boards and processor chips every month. Dollar Bill

MY HUSBAND TOLD ME ABOUT THE GOLD IN THE COMPUTERS, SO I THOUGHT WHAT THE HECK I SAT FOR HOURS AND PULLED ALL THE PINS OFF THE PROCESSORS, IT WAS MORE THAN I THOUGHT IT WOULD BE. 15 CHIPS WAS 8.5 GRAMS, BUT I'VE TAKEN IT TO SEVERAL LOCAL CASH FOR GOLD PLACES AND MAILED IT IN EVEN AND NOBODY WILL ACCEPT IT. THEY ALL SAY IT PASSES THE ACID TEST BUT IT WILL STICK TO A MAGNET. WHAT DO I DO WITH IT NOW? I WAS EXCITED JUST TO PULL THE CRAP NOW I'M SO IRRITATED I COULD SCREAM. HELP IF YOU CAN!!!! THANKS, PATTI Patti Lockhart
