Gold CPU Recycling Yields And Values.

Administrator

Did you know that there is gold in many old CPU’s (central processing units or chips) of old crappy computers? Did you also know that many people don’t know about this or even care? This opens a big opportunity for canny gold investors to acquire a raw source of industrial gold at a fraction of the value of the gold contained in these CPU’s. These CPU’s can be found in dumped computers on the side of the road, at the local tip and are often given away for free at garage sales. The CPU’s can be divided into three classes: From: Southern Highlands NSW Registered: 2009-07-17 Posts: 4,624 Trades : Website

VERY HIGH YEILD CPU’S – Have quarter of a gram or more per piece. HIGH YEILD CPU’S – Have from 1/20th of a gram up to quarter of a gram LOW YEILD CPU’S – Have under 1/20th of a gram

81

Below I will give you a list of some of the CPU types and yields that are available, and put an approximate value on them using today’s Australian dollar gold spot price: ($1440 per ounce - $46.30 per Gram) VERY HIGH YEILD CPU’S: NEC (server chip) - 0.27g - $12.50 per CPU

Toshiba (server chip) - 0.27g - $12.50 per CPU

Fascinating info there. Have you tried reclaiming it yet or are you just stacking the processors at this stage?

No, I generally just stack them, I have sold the chips on ebay in the past for up to 50 cents on the dollar of recoverable gold. I picked up over half an ounce worth (of pure gold content) worth of chips yesterday. 26_100_4318.jpg Last edited by ozcopper (2010-06-19 13:28:18)

Not sure on the motorola's. I have a 6803030 here myself. They are quiet small, but like most ceramic chips, they are higher yielding.

OMG I completly forgot about cpu gold content. I read up on this years ago and forgot it somewhere along the line! If you search youtube you can find videos on how to retreive the gold from them.

I was also looking at PC parts and chips especially however it was too difficult to get to the pins that are plated I thought that was all that was there. To me it looks like there are other parts within the chip that hold Gold. I will look further into what I have. Certainly do not have the qty you have there but it gives me an idea... As for getting the gold off pins and other things it does look very dangerous and you really need the right stuff to do it. If someone knows an easy way certainly keen to hear.

Yes Austacker, the centers of many of the chips contain pure gold. They have really caught onto this in U.S.A: http://cgi.ebay.com.au/486-scrap-ceramic-cpu-gold-recovery-pentium-9-23-lbs-/250648698790?cmd=ViewItem& pt=LH_DefaultDomain_0&hash=item3a5bd39fa6 This means there is an opportunity in this relatively untapped market here for us Aussies

From: Southern Highlands

By the way, RAM also contains about 1 gram of gold per kilo... this is much higher than the 1 gram per ton it tales to get gold out of many major mines.

Are you blessed buggars shooting up smack ! or what ?? . Come on peeps try not to labour my patience . ok ok I apologise . im listening there is alot on google/ tube about this . From absolution it is a wonderous thing to see the particulates fall from a clear solution of moonshine to colou r eh and slosh it into a fal len mud mix and then centrifuge it out by hand or was that the o ther way aroun d ? hehe

Ozcopper, here is a paragraph from the site that may apply to you:

"Cut off those portions of the board that have gold. Discard the rest. Chips, which have gold inside as well as outside, must be broken open. On a small scale, one tap with a hammer should suffice. With lots of chips, you might want to use a cement mixer." Last edited by Jonesy (2010-06-19 22:42:51)

Thanks for this thread ,Ozcopper.It has got me thinking,of course.

In your opinion ,are there any other parts of a PC worth keeping for their metals?I have been reading a bit and see that hard drives and edge connectors could be worth saving.

The whole cost/ benefit ratio thing could be going haywire if gold breaks up rapidly.I have no interest in, or knowledge of, how to extract PMs from these components ,but would be interested in selling to you. I have a friend who is throwing out PCs and laptops on a weekly basis ..he will gladly give me all he has.

An answer from I guy I know involved with a small refiner in Sydney about how to pre-process cpus before giving them to a refiner: The pre-processing for this kind of stuff, as far as I'm familiar with it, is never easy. Basically, the CPUs have very similar characteristics to refractory ores. I don't know whether they also contain plastics, but that would add more work to it.

From: Australia Registered: 2009-07-10 Posts: 635 Website

Basically, the first step (assuming no plastics) would be to pulverise what is possible of the refractory materials. That would be done with a ball mill, the aim being to get things down to as fine a powder as possible with some metal in it. Separation from the balls in the mill would either be by sieve or magnet. If it contains plastics, the plastics should be burned off at very high temperature to destroy any noxious by-products of burning) probably both before and after pulverisation to be sure. I believe that kind of burning is done in southeast Asia. After obtaining a very fine refractive powder & having burned off any plastics, there's a few ways to proceed. I believe (from what I hear) the simplest method of extraction from a pulverised refractory ore is by cyanide leaching. Only problem is it's very toxic! Having said that, many mining companies have facilities to do it. After cyanide leaching, you'd reduce & precipitate the metal from the solution & melt it to form a metal button, then recycle or dispose of the solution thoughtfully. From that point it's very easy to refine. Another way to extract from a refractory ore would be to add a lot of say copper & borax &/or other flux (eg. litharge) then melt while stirring. The desired metals from the refractory ore would dissolve into the molten copper while the refractories and flux would float on top. Once it cools, you just knock off the borax/refractory slag & are

left with a (mostly copper) metal button that can then be easily refined. Anyway, they're two ways I can think of off the top of my head, but I think the first (beside its toxicity problem) is most efficient. Last edited by bron suchecki (2010-06-20 17:24:46)
