I have seen it twice, typical academic paper for funding.
It does the same as AC, but it is effective in acidic environment so maybe if the price is low enough.....

“Analysis revealed that the nugget was made predominantly of gold (90.8 wt%), with copper and nickel contributing 10.9 wt% and 0.018 wt%, respectively. The findings demonstrate the high purity of the nugget, corresponding to 21 or 22 karats”

It may be my math but does the wt% numbers not add up to more than 100%? The gold would still need further refining to achieve higher purity. This second refine would be where I would be curious the most. If it will recover higher purity the second time around it would then have a more viable use I think. Time will tell.

That means it has not been properly peer reviewed or the peers have the same math deficiency as the authors

So, they dissolved the gold in acids (like we all do), but then instead of using a reducing agent like ferrous sulfate, SMB, etc., they used their new whizz bang cheese by product to adsorb the gold and other metals, so they can further refine it... Amazing new discovery!!!

Big cheese conspiracy...

It makes me wonder who actually figured this out? Was it a lab accident or was it someone thinking outside the box. You know, the kind of scientist who has gold in his pee!

Seems like another "green sceme". Like people with their noses in the air, who buy an EV, thinking they are saving the planet. That being said, it will probably be the green way to process, even though we know the real truth. Funny how everybody wants to reinvent the cheese wheel.

Still I would have expected them to get their addition correct at least.

Somehow, I do not believe this is anything new.

Time for more coffee.

Them: Figures out how to collect gold with cheese.
Me: Still just cutting the cheese.

What is AC ?

 

[snoman701]

i think it's pretty cool depending on the loading characteristics.

Peer reviewed? The last few years have shown beyond doubt that peer review is no more than getting a few of the people who agree with you to mark their own homework...

Activated Carbon, it should be logical in terms of what is discussed.

Agreed, there was an incident her in Norway when one of these modern institutes had a pre-release of a research report.
Another group not affiliated to anything asked to have the report fro peer review and was promptly told no, since they were not in the inner circle.
So in other than hard science I don't think the peer review system is robust enough today.
Too much flawed statistics and not enough attempt to break the hypothesis.

Haha so very very true.

That may be true however the abbreviation AC is also used to describe Alternating Current . I asked because I didn’t know.
It’s all in the details
No reason to be so snide about it

Well in that specific reply, I compared the new cheesy material with something with respect to ability to capture Gold,
we were not discussing electrolysis just then.
But in retrospect I see I could have saved time writing the whole name.
And there was no attempt to snide about anything, but as always the Devil is in the details.
But sometimes one need to lift the perspective to get the over all picture as well.
We have all been there I guess.

Guys I saw that article and read it and had the same thoughts. It's just a novel reducing agent that happens to be easily removed as a sponge but you still need AR and you still need to melt the resulting sponge and further refine it. Like yall said it's really nothing new. Not to mention you have to process the whey as well.
