Averege yield per 100g of fiber CPU pins ~?

[DuckTheQucker]

How much Au can be recovered from 100 gramm pins from fiber cpu's, all kind mixed up small ones, big ones, AMD, Pentium e.t.c...
Already washed out from tin.

 

[DuckTheQucker]

Another question to u forum.
Are those dots and lines on RAM slots gold plated ?
Or only fingers ?

 

[goldsilverpro]

On the pins, it would nice to see a clear closeup with a ruler next to it.

 

[bmgold2]

I'd say the dots and lines look gold plated also. I'd scratch off some of the solder mask over the leads (lines) on the circuit board and check if the whole board might be gold plated. Probably isn't but only takes a second to check. If it is, try searching this forum for solder mask removal.

Keep in mind that the I.C.'s (black rectangle pieces in your picture) also contain gold. Again, search this forum for methods to recover it. Should be worth saving.

20 gramms on this picture, wos 22 with tin.
5 Green fiber AMD big
1 Green fiber Pentium big
4 AMD small

Best to do, practise on a low yeild cpu's before u do the big thing ceramics. :mrgreen:

Best thing too do practise on a low yeild XXXXXXXX ones before u do the big thing.

You did read the forum rules didn't you? Hate to see you kicked off before you even get started.

As long as you are going to do a small practice lot, why not blend them well and then weigh out a sample. That way, you'll know what value to expect when you run the rest of them.

Thanks for advise, i tryed scratchng them, plastic.
What about I.C's from mainboard's their legs looks silver or palladium to me.

I'm just getting started on the whole refining game but I've been saving ALL of the I.C.'s I find. I'm up to a little less than 2 pounds so far. From the little bit of testing I have done it looks like most of them have some gold hidden away inside. You have to incinerate or crush them to get to the gold but it is there. Might not be visible since they are VERY thin but every little bit adds up.

Im planing to make home made fumehood with filter, not practising with out it. :mrgreen:

You can't tell silver and palladium from just looking at them. You need to learn how to do some testing.
Silver may tarnish and give itself away on some things. You will be disappointed later if you keep thinking every silver colored metal is silver palladium, platinum or rhodium.

Good catch Jim, I missed seeing that part when I answered.

Grey metal plated on copper base. Im shore its precious.

bmgold,

On each post, there is a big red exclamation point, (!). It's main purpose is so the members can tell the moderators that there is some problem with that particular post. After clicking on it, you will get a chance to state the problem as you see it. The red (!) will then show up in that post and in the menus, but only is seen by the moderators (as I understand it). A moderator will then solve the problem. That's OUR job.

I hate to burst your bubble but it's more likely nickel, manufacturers don't waste precious metals especially at today's prices.

The only white (gray) precious metal I have ever seen on the board, itself, was rhodium plated fingers on some Xerox boards from the 70's, which are as rare as hen's teeth. In modern boards of the "green" age, you might find a little silver in the solder. On the board, itself, you're looking for yellow gold. White gold isn't used on boards. Neither is Pt, Pd, Os, Ir, or Ru.

___________________________________________________________


A story. In the 70's, memory disks were standard on big business computers. These were set on stacks, not unlike records stacked up on a record changer. Some of these were as large as 48" in diameter. They were made of about 1/4" aluminum. A magnetic layer of electroless cobalt (usually) plating was laid down and a fairly heavy layer of some precious metal was laid down on top of that, to protect the magnetic layer. They usually used gold but they would have liked to use one of platinum metals because of their hardnesses.

The biggest thing going on in the memory disk industry was rhodium. Rhodium's properties were perfect. Better than sliced bread. A man that eventually became my partner in another venture was the leader in this. He had the world's largest rhodium plating bath. I worked for the company that sold him the rhodium solution and that's how I met him. It was a huge sale and I spent several days helping to set it up and we did lots of experiments to perfect it.

All went great for a few months and then they started have reading problems on the disks. In seems that pure clean platinum group metals tend to polymerize organics from the air. It was like strong rubber cement. Under the scope, I watched him roll it around in little brown sticky balls with an X-acto knife. It was so thin you couldn't see it just by looking at the disk.

In other words, it would be a mistake to use any of those metals for, say, fingers. The only other white PM is silver. It isn't used for fingers because it tends to form crystals that migrate on top of (or, through) the board material from one finger to another, connecting them.

Thanks GSP - I've been on the forum a long time and never noticed that doodad hanging out at the bottom.

I've never seen the red exclamation point either, and still don't for that matter (other than where GSP explicitly inserted into his reply). Apparently it may only work in certain browsers? I have no idea either what the reason is why bmgold2 was threatening another member with expulsion? Didn't we just get past another one of these incidents? Parts of this group are sure turning into a bunch of elitist nitpickers!

He was warning about the texting lingo.

Subsilver 2 board style is not the default style, but most members find it to be the best. I think everyone should check it out and give it a try. It does get confusing when all members don't see the same thing.

I'm sorry I posted that but it is done now. No deleting allowed either. I wasn't threatening him just trying to warn him. I won't do it again since that is not MY job. We have a good, clean forum and the language wasn't needed in my opinion. Doesn't really bother me but...

As to the red exclamation point, it's right beside the quote button. It turns red if you mouse over it.
