Incinerate in an oxidizing flame, this should eliminate most of the iron.

I have used AP for a day or so just to get the gold pins loose from the CPU. I then take the fiber CPU's out of the bucket and check to be sure all the pins are off. I have just been storing the left over CPU's to process later when I can grind 'em up and try AR one day.
I then filter the AP away and then use a small amount of nitric to get the gold plating loose from the legs. It takes about a day as well. I wash the legs with water by swirling it around in the bucket. The flakes are light so they float away from the heavier legs and I pour them off into a filter.
When all the gold is out, I just put the leftover legs in with the mixed iron scrap cases and sell to the recycler.
Don't give up yet on these CPU's, just try a different method perhaps??

While I do not have any more of the green Intel fiberglas CPUs as pictured here, but most of the other types that I have tried using a cell, I have had good luck removing the gold plating from them. I am waiting until tomomow when my son comes home with his camera so that I can post a few pictures. In the ones that I have tried, I have removed the gold from over 95% of the pins bu just clipping on the aligator clip to several of the pins.
It is very fast and no mess to clean up. Only draw back is the time it takes for the gold to settle to the bottom. It is slow in the thick suripy concentrated Sulfuric Acid.

Really? That is a Bold statement my friend.oef62nd said:
As glorycloud has stated, it might be your way of refining buddy.
You have to remember that their are people that know nothing of recovery from e-scrap. given, there is very little gold in the Fiber CPU's you speak of but there is gold in them.
"Do not buy" Really? .. you obviously have no idea what type of deals are made outside of ebay, huh?
I personally know of purchase's of over 50Kg for .10 per Kilo from freecycle.org.
I do agree that these CPU's have small yield's, however if a person is just beginning with what they have the topic title may be discouraging enough to stop them from furthering their knowledge of how to recover and refine..... safely
Harsh topic that should be treated with respect in my opinion.

It would seem you skipped some steps in processing. You should have removed the iron first. AR is never recommended as the one and only first step. Gold is easily lost in complex solutions. Once you remove as many base metals as possible, then you apply the AR.
Keep in mind you did not destroy the gold present, just misplaced it.

Using AR on electronics scrap is kind of like using a sledge hammer to put in delicate crown moulding. At least we know you're not messing around!
I would probably look at other milder and more selective methods.

Just consider the source. This is the same individual that had to run his mouth when he was advised that "nuking" everything with AR was not a good approach (posting under a different identity). He needs to learn the lessons the hard way. Looks to me like that's exactly what's happening, but he's drawing the wrong conclusions. Such is life when you disrespect those that try to help you.Despotic said:

Yes Harold, I've considered the source. That is, in my opinion, no excuse for
people that are allowed with identity known or not to post , to post, such non-sence at their convenience of others. I would never challenge your authority on the forum but I will challenge such people that post as if they have the "Final" answer or "Final" Word in leading people astray.
I'm sure harold agrees with me on this subject so on to the matter.
You, Sir, Have no business here as I can see. You have given little, if any, to the community except to try and deceive the respected members of this forum with no avail to you sir. Did you really think that the respected community would not respond to such non-sence for you to watch in amusement at the confusion of others that do not yet have the knowledge to call "BS" when it's being spoken? If You continue to act like a moron then you will be branded a moron.
Good Day To You Sir,

I use a chisel to cut the pins off and save the rest for milling and later processing. I refuse to give up on gold I can see. But that is just me i guess.

Yes, and my comments in that regard were deleted as well, a decision I am not pleased to see.
It is important for readers to understand that materials are not always as they may appear. My post alluded to that, and served to send up a red flag for those that get the wrong impression.

Anyone can get some kind of recovery from high grade material with a blunt instrument like AR. But it takes some technical expertise to get good recoveries from low grade scrap.
The goal is to learn the skills and to know the difference. :wink:

How do I deal with these chips? well, for starters they are the lowest value cpu chip on the scrap market.
We are an electronics recycling company, which also buys boards, plastics, chips , memory ect from the public and commercial sector.
As much as i would like to wave a magic wand and get the gold off of those fiber chips, I simply wholesale them to a refiner. thats how I deal with em.
i cherry pick the bins for my personal refining and away goes the rest.
I understand not every one here has the volume of materials or wholesale capabilities. Nor a local place such as my company to even sell these items to on w retail level.
However, just for reference, the green fiber chips were being bought over my scale friday morning at 6.00 a pound. and mixed chiips at 18.00 a pound. sorted chips verry, depending on types.
My post on buying them all day was more or less a wise guy response to a mindless PM i received from a member who was put in place a few posts above.
