Interesting find

[Martijn]

This guys from Ebay charge too much for this PCBs, you will barelly get any gram of gold not speaking about chemicals and time to recover that gold.

He is the guy from ebay advertizing his own PCB's and asked us what a good price should be. He still asks way more than it's worth. He actually did not lower his rediculous price of 99 dollars for one PCB and spams more ads over negative comments.

If you sell your scrap on ebay, you're probably not happy with normal scrap prices, which are in relation to the actual value, so you try to sell it to naïve people for more than it's worth.
Naive people don't ask and just buy and assume instead of thinking and checking.

Well there is no good without evil I guess.
And there is no smart without stupid.

We need some scum to spit on every now and then.

@mikeinrco: Your boards are worth a couple of dollars max.
Stop selling and shipping worthless waste overseas, polluting our world and putting naive people in danger.

This starts to look like some ad spamming for a "overpriced product" this forum do not support. Not a single complain for quadruple postings. I do not support this type of "ADs" since it uses the forum as a typ of reference. Must be good, since in GRF, type thinking

The responses here are comical at best......I have been a member since 2012 and came here offering these items to the community......I said it was easier to post the items on ebay than using a 3rd party picture hosting site,,,,,,,These are multiple listings and have had great response to these boards........Oh well thanks for all the negativity about par for the course around here

With all due respect, can you share with us, how much gold did You personally recover from these boards to determine their real value. Also please share the documented invested time, acids and other materials used to recover and refine the resulted gold.
Just because you are a member of this forum from 2012, nobody has to take your word or anything elese for granted.
Please do not see my post as attack, it is not ment to be one, but when other experienced member say about your product as being too expensive (without any clear indication or real data from you, that the recovered values are far more than the invested time and money, it is a guess at best) you comment it as "..The responses here are comical at best....."
That in my opinion just plain unfair.

Such a poor excuse. It costs one second to make a screen shot and two more post that here. I think you just want to make a profit, that's fine.

I gave several reasons why I think it can be dangerous for individuals and our world's health in general. I asked you some questions and answers are not given or vague or need to be interpreted as I experience it, but that's probably my shortcoming.

Why are you selling a product way over it's actual value sir? Correct your price or accept the bashing! High trees, lots of wind.

I know a lot of people that do not break any laws doing the things they do, but I loathe them for acting that way.

It has to do with honesty, responsibility and care for our fellow humans and nature around us.

A parasite may think, hey, that's how I need to live, but contributes nothing to the collective and actually is sabotaging the system making it rot and stink. That's why parasites need to be exterminated at all times or they will destroy everything you love.

This was a general analogy off course, no call for physical action, I assure you. Verbally, YES!

I will keep informing our dear friends and members about BAD DEALS!

And who knows, maybe trying to talk scammers into creating a little conscience about what they are doing.

Nothing comic about that. Actually very sad it needs to be done. You always have a chance to redeem... go have a good look in the mirror and apologize to all you have sold such treasure to.

By the way, posting your own overpriced E-bay auctions as "interesting find" is misleading at best.

And against forum rules I hope.

Some of the new rules are not quite set in stone, so we are awaiting input from the owners.

Scrace Resources and Circular Economy demands conversion of waste to Values.

It's not the issue of technology but making the right choice & investment in recovering 80-90% of the values like Copper, Precious Metals (Au, Ag, Pd, Pt, Rh, Ru..)

E-Waste Managment is really an interesting and commercially attractive business. Just imagine 25 years back; world depends only mining from nature for every metals to resources but today, every small company able to establish

Best technological approach - Mechanical to Hydrometallurgy
However low grades and if the quantity is big- pyro would be better but investment is huge (pollution control equipments and furnaces)

We have members here saying the opposite.
Pyrometallurgical is the only viable approach for anything more than single items.
Hydrometallurgical approach will seldom achieve more than 80-85% completeness. So the losses will be high, especially with Rhodium.

Rhodium case is different (except it) most of the other metals would be good upto 98-99%. However note of the input materials metallurgical complexity and composition!

i have done tons of gold, silver, platinum, palladium, copper using hydro-metallurgy. Preparation of materials and customized / selective recovery and refining is the point. LAB scale approach is only basic principle which will encourage any big debate on the commercial scale

I know practically nothing about metal refining.
But I do know that most any carbon based items can be vaporized and passed through a catalytic process. And converted to a wide variety of useful materials.
That process would not only create a major new stream of raw materials. Thus reducing the need for petroleum. But also it would concentrate the metals in the feed stream.
Would that not also increase the ease of refining any metals present?

Vaporizing metals will require plasma which will be very hard to do in any reasonable scale, even worse with Carbon itself.
And it will need no catalytic processing, at least the ordinary metals.
So it would be interesting to know where these ideas come from.

That is the most heart felt, and accurate description, of one of the things that is wrong with the world today. There is no emoji to express my like of this post. I couldn't have said it better. Thank you Martijn.

I think you miss read my posting.
The carbon based materials are vaporized and catalyzed.
All metallic items are left behind.
A typical temp for the process is around 1500*f.
It's basicly the process Germany used to make synthetic oils in WWII.

You are talking about pyrolizing.
It is important to use proper naming of both chemicals and processes.
Pyrolize is heating in absence if oxygen.
The Germans introduced steam in addition and thus created syngas which was used to produce syntetic fuels.
It will leave most of the carbon and all metals/metal oxides behind.
It can then be incinerated/ashed to remove the remaining Carbon.

Very nice explanation of the pyrolizing process.

Thank you much for the clarification of the processes proper name.
I read about it long ago and didn't remember that.
Also I was under the impression that most of the carbon was used up.
Thanks again for the clarification.

I guess that can be adjusted somewhat with the temperature and the steam in the original process.
Tehy were looking to make as much Syn gas as possible, we are not.
Fort our use, it is used to decompose and drive off the volatile compounds so we do not poison our surroundings with toxic smoke.
The gases can be bubbled through water and injected back into the flame heating the components and such save on fuels costs as well.
After, when we roast/ash it, there will be no smoke if it is done right.
