If the foam is heavy, judging by the color, it looks like there is a lot of extremely finely divided metals in it. Primarily lead, tin, aluminum, zinc, iron, and possibly even some traces of silver, copper and gold. There will also be small traces of palladium and polonium as well. Pretty much any metal that might be in those boards as well as dirt/rock/sand particles that get mixed in with the mix. Anything that is in the nanometer scale. The foaming is caused by the dish soap you add, plus the electrolyte from the capacitors in the boards. It's causing it to emulsify and froth. You might try dishwasher soap, as it does not foam nearly as much as regular dish soap. Look up froth flotation. It's been used to recover metals for quite a while. You should take the foam, and let it sit in a bucket and let it settle over time and smelt it. I'd be interested in what you'd get.

i wonder if an extra process can be added right after the crushing... some static electricity sort of thing that collects the plastics cause they have a lower electrical capacity (like how small pieces of paper will stick to plastic) or even a wheel with an induced magnetic field, cause even though they arent magnetic - copper and aluminum will respond to an induced charge because of lenz's law - how when generating electricity or propelling a motor there is resistance from the induction itself

Yes, those are older motherboards with BGA cards. The BGAs you tend to want to collect and process all by themselves. They have a lot of gold in them. The mid-grade boards can have relay switches in them, with thick copper coils and little contact buttons with silver or gold, sometimes just a layer, but sometimes solid.

Jason, I love the videos as always! But a friendly recommendation especially when it comes to the higher grade boards with chips etc. Either rerun the material and get it to about 200 mesh (incredibly fine) and you’ll be surprised to see upwards of 50% or more PM yields out of it. The tiny gold bonding wires are stuck in the plastic of the ic chips and majority of your gold will be there usually. Once it’s down to consistency of flour, you’ll actually be able to see beautiful lines of flour gold when running on the shaker table with lower flow rates etc. try it just once, trust me :)

I believe that the first KZfaq content creator that promotes the actual process of transacting in gold and silver will go viral. To completely change the mindset of the average American, they would need a reference point (price) for everyday objects. Ex. "Steam clean entire house 7 ozt silver" "Couch for sale 5 ozt silver" "Babysitting service 1/2 ozt per hour" Every silver / gold stacker should RIGHT NOW go list something they own for sale priced in silver or gold. EVERY KZfaq content producer should throw this idea into EVERY video they create, until it becomes the norm.

So, the sludge like material is the foam insulation glue they use on the boards. That white cream stuff you see on boards w/ batteries, wires, etc. And looks like glue but it's foamy. The stuff you got, put it in buckets to air out and settle. Once it's powder again, run a magnet through it. Once that's done, the rest of the process is either sifted through and roasted or sifted through and runned through a chemical process to sort out the metals and melted down later. And once the foamy stuff has been officially sorted out from all metals, it gets tossed in the trash because it's not biodegradable. As for the board info, you're just about spot on. As for dry or wet weight, do both and see the difference. I personally don't know, but that's how you settle an argument. Do both. 😉 As for heat sinks, they're best to be pulled off or taken off the board and just set aside for resale or melt. Steel and cast aluminum will definitely bust up your equipment and get stuff stuck into said equipment. Don't want/need that. Like hey, you wanna stick an engine block in there? Uh, no...! Why? Self explanatory. 😁😁😁🤣🤣🤣 Good job though! Love seeing you do this. 👏👏👏💙💙💙😁😁😁

In my experience, dry ore that has been sitting for a few days can be 0.5% water by weight. Wet ore that has been drained can tipically be just under 20% water by weight. Drained black sands concentrate can be in 7% or so. I'm gessing drained metal concentrate from a table can be 2 or 3% or so? Interesting experiment (and an easy one).

@zenginellc Жыл бұрын

Ore also contains porous rock and sediments. This is mostly pure metal, which is effectively NON-porous in comparison. I am still curious to see a real test/example on this though, since there could be other contaminants in that slurry which could be an unknown variable that might change the outcome.

Jason, you can try spraying the foam with a high alcohol content mister. Separate the foam first of course. That should dissolve a lot of the adhesive and epoxies that can cause a lot of the foaming. But I can promise there are some valuable metals caught up in that foam. Skim the foam into a separate bin, lightly mist with alcohol. Mix it up a little and do it again. You should end up with a thick sludge after a few repetitions. Let that dry out, break it up and run it through the smelter. I know you always wear a respirator, but WEAR A RESPIRATOR when cooking it. You should end up with some ash, maybe a few small metal beads, and a little “sand” afterwards. Run that over the table again and you’ll not get any foam, as well as a pretty decent metals return.

Foam? Good question. It looks a lot like the foam I have seen on the ocean beaches at times, and it was VERY oily and sticky . I think it may contain a lot of oils, surface coating materials from the boards, and such. If you think about it, fiberglass resin (Boards are fiberglass) is a petrochemical product. I know from my decades of electronics repair that some boards do feel greasy. Also one must take into account the electrolyte used in the capacitors. In some capacitors it felt "oily" when it leaked out. Possibly it is a chemical reaction to all the different materials being mixed together. Just guessing.

@pozdroszejset4460 Жыл бұрын

Cool video! I've seen a couple of other ones and like I particularly enjoy watching old electronics get crushed up and properly recycled instead of getting burned. Could the bubbling up come from chemical reactions between electrolytes in capacitors and pure metals from the rest of the components? Some sort of gas getting released when juice from crushed caps joins the party? I did not see any in the video but if a rogue coin battery or two on a few boards made it to the shredder that would add to the gas problem. If that happens lithium reacting with water will release a lot of hydrogen and steam. What the gross stuff that keeps the foam up I have no idea, maybe the products of the reactions precipitate from the water solution. Maybe it would be possible to mitigate this by adding some kind of anti-foaming agent to the water (idk if you'd need a lot that it changes density of the liquid enough to mess up the physics) That's my wild ass educated guess anyway thanks for coming to my ted talk lmao

The Foam. I have an idea it is a mixture of oils and liquids contained in the electronic capacitors: PCB powder, component adheasives (like the glue used in transformers to separate the plastic and paper sheets of the windings), many adheasive residues from insolating tapes, even some soldering flux, and rosins. I am sure amounts of all would be present in the mistery foam when analyzed for its PH and chemical makeup. As you encounter older E-Waste industry-resolved hazards of the past, they will find their way into your processing work environment. Modern samples will not contain substances like Pb 207.2 {lead} and asbestos, so proper PPE should be employed when the hammer mill is in operation and handling dry consentrates, as the dust could cause a number of health problems. Older e-waste LCD TVs and PC monitors that are black-lit with micro-floresant lights will all contain meurcy (a super small amount, but it would bond with gold in your recovery process, leaving the operator liable to disclose this contamination to customers and employees so proper handling of contaminated materials can be utilized). You could do a control presort, removing any of the elertolitic caps, and see if the foam is still resistant. Also, a detergent like Extra Strength Dawn might preswade the oils from the caps to bond with the deturgent instead of the PCB dust, leaving the dust in the water solution to precipitate out of the solution. The dawn will also help release the surface tension of the water in the system.

First a quick overview of what is in a naked PC board before components are even placed on it. From the middle out a PCB is a series of thin layers of a special fiberglass-like material and epoxy. The PCB is built from the inside out in layers, each with copper traces or large ground planes (the layers where you see large portions of solid copper visible through the epoxy. Often, the first layers laid down are the ground and power planes. Most motherboards are made of between six and up to 8 or more such layers. On the final outer layers on both sides of the a solder mask is silkscreened on (simplifying this part). The board is then dipped into a bath of solder to coat all of the visible surface mount pads and through-hole components like large capacitors, etc. Here’s the next important thing that may be causing this this foam is next. A tacky form of flux is screened onto the two sides of the board. This is used to hold surface mounted components placed by a “robot”. Once this is done, the mother board is heated up to liquify the solder placed earlier. That’s a little long winded I know but few people really know just how much work goes into just building that mother board. When the motherboard is crushed all of those carefully laid chemistry are suddenly turned into mud and water added to them you will get chemical reactions. This includes gasses, adhesives released from the manufacturing process and who know what. The fact that after the tailings settle down, you essentially have made a concrete slurry. And I forgot to mention, to make electronics more “green”, water based solvents are incorporated into the production process whenever possible. Exposing those solvents to water again can’t be good. Assembled circuit boards are an amazing piece of engineering, they just aren’t designed to be disassembled by bludgeoning them into mud. My $0.02 keep or discard.

@urbanprospector3007 Жыл бұрын

Collect the foam into a 5 gallon bucket and let it settle out. What I think it is, is the adhesive used within the board layers. I wonder if any metals stick to it and need to be rerun as a result. If you get anything to settle out in the bucket, it might give you a partial answer. Think of it as the "drost"? You skim off when casting. Just my thought.

20:16 sorry to say, but skimming that junk it your best bet because then it is removed from the system. I recommend a simple kitchen strainer for ~$5 24:28 have you considered modifying a vortex dust seperator for sorting the metal & bplastic from the tailings?

Put rinse aid in your water. It will break the surface tension. It might make bubbles, but they should be clean.

Try a pool flocking agent to drop it out of the water and to the bottom of your container there may be heavy metals in the foam

Generally, you don't want to grind up boards like this. What's your focus? Are you going after the copper or the PMs? These boards should be broken down more. At very least remove all the electrolytic and tantalum capacitors but if you can remove ferrous and all aluminum it will help. If PM recovery is priority then all the items rich in PMs should be removed and processed separately. What's left can be hammer milled and sorted on the shaker table for copper recovery. Some gold will be lost here as it's bonded to the epoxies and washed away in your #4. If you remove ICs, and transistors first you'll greatly reduce the gold loss in the end. Do you have plans to assay the four fractions to see where the PMs went? I think you'll find some gold in #3 and #4 Also, don't forget there will be plenty of silver in these boards locked up in solder and components Great videos, I'm sure you'll figure out the magic process, you certainly have the right tools to do it

This is just a guess but I think the foam is the electrolytics from the capacitors reacting with the water.

@Alondro77 Жыл бұрын

Almost certainly. Those canister aluminum caps have lots of different chemical electrolytes in them. I pop them all off and burn them in a tube furnace made from a cast iron pipe. Many of the electrolytes are non-aqueous hydrocarbon-based compounds, and they burn like rocket fuel once super-heated! You can hear the caps pop and roar like little rocket engines as the stuff burns off.

Question: Is it cheaper to filter out 10% aluminum out of 90% copper or 90% aluminum with 10% copper?

@rodger3641 Жыл бұрын

The water issue, if we had a ship worth of dirt containing water and we pay by the tonne for the dirt, we would end up out of pocket. Our assay dept weight, a sample from the ship, then dry it and work out how much dirt and water there is, we don't pay for the water :)

As much as I would like to agree with everyones assesment of the " foamy sludge" it is a by product of the mixture of oil and water. When run through your system with the surfactant the oil is broken down to a degree. The " spray " of water mixes it to a very fine combination of the two. Oil is denser than water but floats. Plastic is a petroleum product. thus making it more difficult. I am sure your filtering system is good to reduce the amount of particles that enter it but the oil/water/surfactant mixture still passes through. Constant recycling of said mixture will produce these results. And to further back this simple science claim you even stated in previous videos of the same shaker table the same setup, " there is a bit of oil that refuses to let the heavies sink. thats why the plastic sheet." I have no instant cure for this other than a complete purge of the system and possibly a second settling "tank" that will fill from a lower level therefore leaving said sludge in the first settling tank. I also believe that you can place a filter of some sort to further filter out the oil from the water. I'm just a simple Electrician and Gear head. When ya blow a head gasket? the water/oil mix turns to mud.

on the wet v dry copper you are entirely right the copper is 99 percent of the weight if the water is drained off, if not it's over 95 percent of the weight

Would there be any benefit to rerunning your #2 and #3, separately, on larger batches? Doesn't seem like there's much to save from the #3, but maybe that #2 could use a better separation of metal type and plastics removal. Edit: Hah, guess I should just finish watching the video before commenting.

It would be interesting to see the density of the #1, #2, and #3. Pretty easy to measure volume in water, and you already have weight.

I would say if your goal is to smelt for an accurate weight and presmelt is just a round about figure then it does not matter if it is wet so that point becomes moot.
