how much gold per kilo?

 

[g_opolis]

I've seen recent posts claiming 5-6 grams per kilo on just the black part, Seems a bit high to me, but......?

hi arthur

well its not a processor, its a series of Ball Grid Array chip IC, i got 5-6 grams of gold per kilogram.

thank you.

 

[arthur kierski]

thanks meng for the information--i have many of these ball grid array ics

thank you.

how did you process them? thanks. alan

crush and mill to 200 mesh.
treat with HCL for a few days
water wash .
leach gold with AR

I have been reading posts about these chips & I am a little confused about which part contains the most gold. Is it the ceramic top or the fiber bottom?

 

[patnor1011]

some of those have plastic top and fiber bottom I couldn't find anything in top part. I have about 180 smaller ones and 80 bigger ones sitting in HCl for about a week now. When I was removing top i applied little heat and then it was easier to separate them. I do not think that anything is inside those black top parts.

We are talking about chips pictured here. You are talking about chips from some other thread. Post some pictures of what you mean.

I would like to see that.
No offense but I am pretty sure I have never recovered more than 1 gram of gold per pound of those.After processing over 10 pounds,I chose to sell them instead.

mic, if you don't crush them to powder you will never get all of the gold.
there are tiny gold wires encapsulated in the ceramics.


but hey... if you don't want to process them i can buy them.

Can I do these with AP? And if so do I need to add heat?

"Tiny gold wires encapsulated in the ceramics", that is what I wanted to know!
Thanks.

Thanks.

Not all ceramic cpus or integrated circuit housings contain gold wires. Be sure to do small scale testing before you spend a lot of valuable time harvesting and processing the worthless type.

Thanks for the advice.
I am referring to chips like the ones in the picture at the beginning of this post.
I am also saving up some "flat packs" & older ceramic DIP chips to experiment with later on. If I get rich with those I will be sure to let you all know.

That was after crushing them.I have been doing this long enough to know that.

I have about 3-4 pounds of them right now if you are interested,make me an offer per pound,and we'll see.But do it on a PM.

If we are talking about BGA what are on first picture in this thread or like on my picture I do not think that they are ceramic. Black material on top (already removed on first pic) looks more like plastic. If removed carefully f.e. with application of heat there is nothing inside (that black part) and it is called mold compound and it is there to protect wiring and die in fiber part of BGA chip.

There might be good yield from those it depend if we talk about their weight with solder or not. I prefer to cut that bottom part with knife and then I have less solder to deal with in solution.

a bit of reading about them:

[patnor1011]

And another thing to consider is that there are thousands different types of BGA chips:

The ones Arthur is asking about can very well be in range of 5g per kilogram.

Okay guys, looks like I have made yet another mistake. I didn't look closely enough at the first picture, I have the chips like are shown in the picture that patnor1011 posted. I am learning.
