Looks pretty pure, but I can't really tell from the video. It's too far away to see. You could post a picture of it close up.
Some comments:
Your process is very dangerous.
Wet ashing, toooo much nitric, BFRC coming straight for you shortening your life span, no fume control. No catch basin.... and lots more room for improvement on safety.
You can save a lot on acids.
A hot ait gun inside the beaker while laying on its side could blow out gold powder.
How do you handle the toxic waste?
And warn viewers of the dangers in your video. Not to repeat at home.
Be safe.

Martijn.

I only watched the first part of the video, I will watch more later when I have more time.

I can see you are doing what you can to work safely, I was also concerned with safety, consider putting your pants over your boot tops, I can just imagine a boot full of acid. Roll the tops of the cuffs of your gloves, so when you raise your hands the acid does not run down your arms.

I'm suspecting that "waste management" is done by the nearest river or lake.

Taking a stab at someone's credibility by stereotyping them isn't okay. I've seen a lot of stuff like this over almost 11 years on the forum, and I've never said anything. But sometimes they get under my skin.

They should show what they do with their waste, as they went through the trouble of making the video showing everything else. Youtube viewers need to see that. Or they will follow what has been shown and dump the waste where ever.

Couldn't agree more. . . take a quick look at "Dr. xyz" posts. I have and I couldn't find one that was of a positive nature.

Guys, that may well be right regarding his posts.
They are however usually on topic and largely correct in what I can remember from the top of my head.
Gloomy and dark but to the point as the Fins often are portayed in films :twisted:

We have seen quite a few of these youtube videos fron the south western part of Asia,
with total lack of safety and so on, so his observation and comment may be warranted in that scope.

But you guys are correct in that we should let the benefit of doubt come first,
and ask him what he do.

Best done in a PM maybe?

I hope he replies with a picture.
Love seeing gold. Many do.
That's why i felt obligated to make some comments to his video and the way he works.

Giving your you tube channel a boost is fine but the most help wanted posts here are caused by people trying to replicate what video's like this show without the warnings.

I see a couple health an evironmental risks he could control a bit better. Let's all get better at it.

Martijn.

Hi

I ran 305g of green piece under the BGA chips and got 0.25g gold.

So that makes my yield from them 0.8g gold from 1kg of them.

Here are the pictures

Hi,

Can anyone explain me how much yield get in per killo/lb this kind IC Processors, image link bellow

Thanks

I have 50 of those chips I removed from a board a few weeks ago. I'm going to process them today. I'll post what my yield is, MINUS the caps. I'm processing my caps together I've accumulated from other ceramic cpu's. But those caps seem to have a nice amount of gold around the outer edges. I forget if they're magnetic or not. I'll post that info too.

Sorry, but I've been busy the past few months.

The gold recovery yield I got from 50 of those ceramic chips was 1.3g, and not including the tops.

You deserve some time off.

Thank you for your continued hard work and shared information!

James, i can't wait to continue... i will rest for this weekend - and i will continue in monday. And thank you again for resolving mystery of "little elf shoe" here... https://goldrefiningforum.com/phpBB3/viewtopic.php?f=49&t=27544#p290938

I forgot to add some more data about this last test i made (Intel BGA - type 1). Actually it is 492-pin BGA chip - so naming this class of BGA's like that is more precise terminology and easier to remember/recognize it.
They are found on older motherboards - i saw many Socket 370 (and older than that) motherboards having 492-pin BGA chip.

And again, 14.77g of gold /kg and 0.0282g of gold per chip for this type of BGA's - brings this BGA type of chip at first place for gold content based on my tests (so far).

Looks like the 440BX is one of the richest chipsets (Pentium 3) :p

Interesting to know what percentage was in the next generation of chipsets (Pentium 4)?
What percentage is in the north bridge i82850, i82845, VIA VT8753 (Socket 423, Socket 478). And in the south bridge i82801BA, i82801BA, VIA VT8233(A/C).

Most likely the gold content in the chips has decreased, though maybe not.

I also wonder how much richer or poorer the north bridge is than the south bridge?

Maybe there is such information on the forum, I haven't found it yet :)
