Pentium pro processing

[moshik3]

Hello,

I've read there's near 1g in pentium pros. of course that depends etc...
the ones with the gold square on top

can i process them this way -
crushing them with a hammer or in a blender,
then throwing the powder in aqua regia ?

or most of the gold is on that top square and it wouldn't matter if i crush them or not...

thanks for helping !

The top plates go in the Gold cell. Do a quick search of the forum and you can find out more about how to process the rest of it. If you are looking for 1 gram per processor, you will be disappointed. :|

OK i did a search and i see that the realistic is 0.5g per cpu,
and also, the more you grind them - the more gold you can get.

what is a gold cell ? why can't the top plate can't be processed with the rest ?

can i also mix karat jewelry with CPU dust in one refining batch ?

Hi Moshik!

Go to Lazersteve's website for a video of a gold "sulphuric" cell.
http://www.goldrecovery.us/

"can i also mix karat jewelry with CPU dust in one refining batch ?"

No, they should be processed separately.
The jewelry should be inquarted, run thru nitric to separate base metals & the gold sponges thru AR.
Do some searches on "inquarting" & continue reading the information available on how to recover & refine PM's from jewelry & from e-scrap (cpu's).

Take care & be safe!

I got the SubZero kit from Shor.

what would be the stages ?
Shor have a tutorial talking about CPU refining using this kit -
http://www.ishor.com/subzeroinstr.php

what steps would i need to add to it ?
and why jewelry is different, if with CPUs you also throw them in AR fully (with ceramics, other metals etc...)

thanks !

You should familiarize yourself with the dangers of Sulfuric Acid before you use it. It can be very dangerous if you are careless, especially around water. The videos on Steve's site are very helpful on the use of the cell. There is a link to download a free copy of Refining Precious Metals by Hoke in my signature line. You should get a copy, you'll be glad you did.

Moshik, if you read thru the posts, of testimonials of former shor users, you'll find that they had nothing but trouble wiht shor.
Most people buy shor before they come across GRF, & most find GRF because shor is not "working" for them. You can still use some of the chemicals, but the processes for recovering PM's from different sources is better explained here by our experts. If you search & read thru the post you'll find why.
Someone once said: "there're more than one way to skin a cat"; some are more efficent than others & safer. As a general rule, if you intend to RECOVER gold, it's bets to separate the base metals from the gold first.
For jewelry, here are some pic's to help you undestand the process, but please search & read first, before undertaking the process.

You'll find that for the CPU's the steps are different.
All the right information is here, take the time to read it, you'll be glad you did. 8)

Take care!

i'd be very thankful for a link to a guide for refining karat jewelry, and another one for refining CPUs gold..
i tried the search but it is very ineffective,
as you say there are so many threads and methods, that i can't know what one is the best.
thanks for pointing that out !

actually, CPU's are shorter of a process because they dont need to be inquarted ?

and karat jewelry needs separation of the base metals and then continue as the CPU gold (AR) ?

"actually, CPU's are shorter of a process because they dont need to be inquarted ?"

Not necessarly...
There's some information here on how to process different types of CPU's.
http://goldrefiningforum.com/phpBB3/viewtopic.php?f=39&t=9693&p=92886&hilit=cpu+refining#p92886

"and karat jewelry needs separation of the base metals and then continue as the CPU gold (AR) ?"
This is some detailed information I have compiled for processing jewelry scrap.
Go to "Gallery" (its now on page 4); click post "13gm gold slug", download "inquarting" attchm'nt that's below one of the pic's.

Hope it helps.

hey just a question -
why not do the inquartion with copper let's say ?
i'm sure you can recover the silver too, but still... ?

 

[philddreamer]

It takes 2 to 3 times more nitric to dissolve copper;
plus you would be refining your silver at the same time, if you use silver to inquart.

The silver digested in the niric process you would cement with copper. It would be about .99%. This cemented silver then you would run thru your silver cell to refine to .999.

Moshik3 you have a lot to learn but you found the right place to do that, yes there's a lot of posts but all the questions you have asked so far have already been covered and in most cases many times. In answer to your question about inquarting with copper Philddreamer gave you the main reason to use silver but it also acts as a carrier for any PGMs in your karat scrap, more questions?

I suggest you start by reading C.M.Hoke available free as a download off several members signature line, Claudie and Palladium are two who leap to mind, then read the safety section here on the forum, visit lazaersteves site and read the forum handbooks again available free. By reading and understanding these books you will have the answer to most of the questions you have already asked and many more that will follow once you start your recoveries and refining.

We aren't unhelpful but do expect new members to do their part and get up to speed getting a basic understanding of the terms and processes involved and using the correct terminology and language, correct spelling and grammar also are a must, as well as you can manage,as different word endings can mean totally different chemicals and many we use are extremely dangerous especially when mixed or heated or during processes when new compounds and gases can be formed.

Welcome to the forum....
It really can turn you into a very able and successful refiner but it takes time and lots of study.

Actually it takes 4 times more nitric to dissolve copper then it takes to dissolve silver

Its important to know & understand this so you can calculate the amount of nitric you need to remove most of the copper &/or brass without putting silver or Pt/Pd into solution in a situation where you have a lot of base metal that needs to be removed before processing the PMs. An example of this would be contact points nipped off from there buss bar’s (like the small ones from washer & dryer timers) In such a case you have “about” 70% base metal – “about” 30% PMs.

You can remove most of the base metals without putting PMs into solution (because they cement back out) and that way when you do dissolve your PMs you have less solution & a cleaner solution to recover your PMs from.

Thank you gentlemen for your input!

[moshik3]

actually i have discussed the issue with shor,
they say there is no reason not to dissolve karat jewelry directly in aqua regia (or subzero+HCl),
this will maybe take longer but it will do 100% of the gold...

I wish you luck. When you hit the first problem,which won't take long, let's hope Shor are as helpful.

 

[philddreamer]

I now 2 persons that bought shor & gave me their chemicals; I ended refining the material for them. What happened was, that when they ran into problems & called shor for assistance, shor wanted MORE MONEY to "help" them with their problems.

HAH! :mrgreen:

Some people only learn by experience, which may not always be the best way, but is the most effective.... :|

Experience tends to be a very cruel teacher. It delivers the test before the lesson.

Did you read HOKE?....I gues not...
Average computer yield.....just guessing...and skills ...methods of processing.....not for you
Let's taking by numbers,ok?

1)Everybody dreams of troy unces in "one single computer"....wrong.
2)Giving the fact the they "belive"....in so much gold...they purchease something like SHOR
3)Nobody understand that recovery of PGM and refinery are 2 different things
4)Sorting things before(intense labor) gives you less headache
5)Entering this wonderfull FORUM ,who has members with years of experience....just "SEARCH"....it's FREE
6)No gold in the entire world is going to buy back your health....so be SAFE
......
And by the way....:
a)Read HOKE
b)Steve DVD'S is an wonderfull help
c)Harold is allways near you(but watch the "******" language)...and other members too
d)It's just a HOBBY....for fun(it's wonderfull,exciting,expensive and health treathfull)

BE SAFE ....
