Iron in microprocessor pins

[Anonymous]

I've collected a bunch of processors. I read that in some of them there is iron which means they're no good, but pins from all the processors are sticking to a magnet. What's going on here?

The thin nickel layer under the gold is slightly magnetic.You should notice a difference in
the magnetic attraction to the "bad iron ones" and the better ones.I think it is the Pentium 3
and newer ones with the iron pins.The older ones should be the better ones.
I haven't processed too many processors,and just sell the iron pinned ones.

Thanks for the insight.

Just FYI
When I use the Modified Poorman's AR recipe & procedure, you can effectively process gold-plated iron pins. You need a bunch to make it worthwhile, but HEY! @ $1276/oz. ALL gold is good, if you can justify the time spent.
just my dos centavos.

What are the difficulties to process pins containing iron?

the iron & carbon, both from steel can be a complete b**** to filter, as both can be used, unselectively, to drop values.
you can't just put them in solution & leave them the way you can copper-based ones. They aren't too bad though,
if you use the modified Poor Man's Ar recipe & procedure.
the yield isn't as good, either, probably, but I have plenty of time & not enough gold! :lol:

I think the most important thing is,if you are going to process any
of these "iron pin processors"for you to keep them separate from
the others to make things easier for you.Save them up until you
have enough for one batch of just that type.You don't want to
introduce any problems from them into your "good processor"
batches.

EXACTLY!
