Pulverizing Electronics, Recovering Valuable & Precious Metals

You could check the pH of your water before and after grinding the lithium batteries. The lithium possibly ends up in dissolved in the water as lithium hydroxide. It will make the water alkaline. When you evaporate it next time, you might see salt crystals.

The specific gravity of Lithium is only 0.53, and lithium oxide is 2.013. Fiberglass is typically 1.0-1.8. That means probably a lot of that black stuff going into #4 is lithium oxide, which the customer probably wants to catch and separate from the fiberglass and plastic. You probably need to re-tune the table for ultra-light materials, and re-run the #3 and #4 fractions to recover the lithium oxide.

[@illinoiseyplay]

[@tabascoraremaster1]

gravity ? It's called; specific weight.

[@TheAruruu]

@@tabascoraremaster1 No, he had it correct for the numbers he provided. "The specific weight, also known as the unit weight, is the weight per unit volume of a material." "Relative density, or specific gravity,[1][2] is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material." Weight depends entirely on gravitational field strength, while mass is constant.

[@buckstarchaser2376]

The black stuff in the batteries is graphite, which forms the positive electrode. Smashing a lithium cell in air and water is going to send all of the lithium compounds to your lightest bin, as it's going to be less heavy than plastic. It will be in the form of lithium carbonate (by the time you find it), which is a white powder. Probably the easiest way to harvest it will be to let your water settle, then drain it, then evaporate the water for its residue. Lithium carbonate has a solubility in water that would likely exceed 10 battery cells (18650) per liter of water, which you clearly have many times that much in your system, compared to the number of cells in that bucket.

[@leonidas953]

Second Buck’s comment absolutely correct.

[@Raviniax]

Regarding the batteries: There exists several different kinds of anode and cathode materials which are used in rechargeable lithium-ion batteries. Cathode active materials include LiMn2O4, LiCoO2, Li-NMC-O2 (mixed Ni-Mn-Co instead of just Co), LiFePO4 and more. Most common anode material is probably purified, spheroidized graphite. Majority of the lithium is associated with and carried on by these heavier cathode materials (density something like ~4-5 g/cm3 iirc), except for the Li present as electrolyte salt (and any Li still intercalated in to the graphite) which would mostly dissolve in water, depending on the quantity of H2O vs. solids utilized. My understanding is that these cathode powders are mixed with carbon black (fine carbon powder, to increase the conductivity) before applied as a slurry (powder + PVDF binder + solvent for the binder) on the cathode aluminium foil. At least the batteries which contain oxidic cathode materials utilize organic electrolytes (not water). The electrolyte is usually composed of an organic solvent (I'm aware of different kinds of liquid organic carbonates, e.g. dimethyl carbonate) to which a charge carrying salt is dissolved. This salt can be e.g. lithium hexafluorophosphate. My understanding (possibly flawed) is that the polymeric separator membrane between the anode and cathode houses this electrolyte solution. I would be careful and avoiding exposure to the generated solutions as they might contain dissolved fluorine and lithium from the electrolyte. These solutions might be pretty rough on the equipment as well and cause corrosion (similar if you happened to have chloride-containing process solutions). Most of these oxidic materials are black (the oxidic cathode powder on aluminium foils). Graphite is also black (anode powder on copper foils). Therefore, the color of the materials might tell less than expected. Thank you for the video, this was very interesting to see in practice.

[@leftybickel9877]

The flat packs are ic chips, some are indeed called flat packs but are a little different, you are correct that the gold comes from the wire, they are called bonding wires that connect the chip that sits in the center of the package and makes the connection to the legs that extend out of the package.

One electrode is coated in carbon. Thats definitely black. The other is coated in a Lithium compound that also looks dark. So I guess the no. 3 black stuff is carbon and the no. 2 black stuff is the lithium.

Some of that is also Cobalt compounds, and there is probably some Manganese in the mix as well. Or maybe not, it depends on the chemistry of the cells 🤷‍♂

[@technosaurus3805]

The black goo in most batteries is manganese dioxide powder with an electrolyte such as potassium hydroxide solution while the black rods are carbon and the black sheets can be graphoil or just a separator or collector with either manganese dioxide or black nickel oxide embedded in it. Either way the wastewater will end up being a relatively caustic base. If you process lead acid batteries at the same time, the wastewater may be less caustic since the sulfuric acid can combine with the lithium, sodium and potassium hydroxides to form sulfates. Either way it's gonna be rough on the hammer mill and other equipment.

AFAIK lithium reacts with water to form lithium hydroxide, which is a strong base, not an acid. I don't think it really attacks the metal. The electrolite in Li-ion batteries are organic solvents, which are probably not very healthy but also not highly toxic.

The legs are almost always tin plated copper. Tinned copper is readily soldered, and doesn't tarnish or corrode as bad as bare copper. Chips can be "decapped". For plastic, I've seen it done with sulfuric acid. Hobbiests, geeks, engineers have uploaded vids of them decapping chips, and examining them at high magnification.

Well, what you are seeing in the #1 bag that looks like pins or needles is solid gold pins off processors and some expensive IC's.

Copper, aluminum, current collectors. pvdf binder, pvdf or ptfe separator, and the casing material Anode- likely spherical graphite with (~2-5% binder), if newer than 2018 and they could have some silicon nano particles for increased capacity. Need fire or n-methyl-pyroiodone to remove pvdf binder. The smoke fumes will have fluorides so be careful with that. cathode (grey black) cobalt, magnesium, nickel mix- likely a cobalt heavy or 333 mix for older batteries(metals precipitated together as a single particle). also contains a 2-5% pvdf binder Lithium will be oxidized, or intercalated into the graphite or cathode material. Electrolyte contains ethylene carbonate (solid at room temp) and diethyl carbonate(liquid at room temperature), new batteries also have ethyl methyl carbonate for improved low temp function( flammable liquid @ room temp) The nastily material in the electrolyte is lithium-hexafloraphosphate which acts as the salt. The fluoride in the salt stabilizes the molecule and helps to prevent breakdown over time.

Hi Jason, I've read about half of the comments - didn't see any mention of the metal Tin.

In the bucket of IC chips - the chips that have legs on all 4 sides are the flatpacks. The chips that are rectangular with slightly larger legs on just 2 sides are called in-line chips.

The computer chips( flat packs,) have copper pins coated in nickel or tin, and haveva silicon die connected to the pins with tiny gold wires.

[@KrazzyKlown]

20:40 The tinning on the pins is probably solder. The lead in it would make it heavy.

[@scrapman502]

when you were processing the gold plated fingers and circuit boards, there were a lot of what looked like flattened metal beads. That's most likely the through-holes which are actually filled with Lead or tin based solder. They would flatten out rather than breaking up into small bits because Lead is a soft metal.

[@richardfellows5041]

We have not used lead based solder in electronics manufacturing for many years (ref RoHS) , so most likely through holes with current non-lead solder.

In the batch 2, the integrated circuits contain silicon, some rare earths and very fine gold wire that go from the circuit to the pins. The silicon chip is glued on the support with a special glue, then the gold wires are soldered and all is moulded in hard plastic. Watching a video about manufacturing IC will be more efficient than my explanation. Recovery of rare earths like germanium, yttrium etc seems to be be very complicated, but it's maybe worth to try.

The black flat packs and such. Some , but not all have gold bonding wires extending from the legs to the the silicon wafer (chip). The chip is mounted on a metallic base plate that is plated with a precious metal. The plating used depends on the function and manufacturer of the chip. Back to the bond wires, they are so small they will float on water, very tricky to recover. The legs in most cases are nickle. Sometimes plated with gold or sliver. Again it depends on the function of the chip. The #3 from the flat packs will likely contain a good bit of gold wires still encased in the black epoxy

When I worked in a pc board plant I worked in plating and another metal we used was nickel so there is probably a lot of that in there as well. When I work in edge plating I would have at least 20 oz of powdered gold in the cyanide bath at one time, even though the layers were thin it didn't take a long time to go through what was in there, the chemist would constantly take samples and use a machine to test the thickness of the gold on the boards to know if and how much gold to keep adding to the bath as you should get a specific thickness per a given time in the bath. You can use magnets spaced strategically to separate ferrous from non-ferrous metals. There is an interesting guy with a channel on youtube that swears he can even set a sluice box up with magnets to increase your capture of flour gold because even though it is non-ferrous the magnet still does have enough effect on the gold enough to push it to specific areas. If you are interested I can find the link to that video.

As an electrical engineer this is super interesting to me. Very interesting to see a way to recover the precious metals that are used in IC and PCB manufacturing. I'm not an expert by any means but might have some answers to your questions. In response to the colors of metals you are seeing. Most PCBs will use copper layers and on the connection points the copper will be plated with gold, tin, lead, silver, nickel, and germanium in different alloys and chemistry depending on the application that the PCB was designed for. The things you were referring to as flat packs are mostly flat packs from what I could see so right on with that. Also saw some DIP, SOIC, and QFP. I usually just call them ICs or integrated circuits because there are hundreds of different kinds of packages in modern electronics. Many ICs use a technology called bond wires and they are usually made of very fine gold wire that connects the silicon die to the lead or pins on the plastic packaging.

The pins are typically Cu, or Cu / Be alloy (for tensile strength), and are plated with Au, Ag, Sn, or Sn / Pb alloy depending on age and use of the pins. If one is recycling relay contacts, one might find Ag, Ag / Cd, Cu, or Cu / Be metals. Of course, all this is subject to change as various alloys are substituted depending upon usage, tensile strength, and current carrying capabilities. Aluminum is used much more in current devices and applications. The round blobs are probably the through hole copper plated conductors which may or may not contain a plating of Sn / Pb. The separation process looks really good and electrodeposition, Aqua Regia with chemical purification or direct gold smelting look to be good recovery methods for your turnkey circuit board or integrated circuit processing plant. The metallic content of the connectors and pin strips will the same content as the boards and have a lot of plastics (PVC, CPVC, ABS, and even UHMW) included.

[@snarky_user]

Regarding the "black stuff" in those batteries, it's likely that there is more than one type. There's probably a large fraction of graphite, with another fraction being metallic oxides. Therefore, one wouldn't necessarily want them to stop be in the same pot. There may actually be many types of black stuff that could be separated into further refinable portions.

[@vicroc4]

If they were Li-Ion or Li-Poly batteries, the "black stuff" is probably mostly oxidized lithium. Which would make sense as to why the bag with mixed "black stuff" and copper was lighter than the one with mainly copper - lithium is much less dense than copper.

Im guessing the gold is such a fine particle size as it will be very thin and as soon as it encounters shear forces it will forms flakes. Do you have an x-ray fluorescence gun? Pointing it at those packs would be very interesting!

Great Video and Ready To see the Next step with the Material

Pretty sure the black stuff is just graphite. I guess it MAY be a copper oxide or some exotic metal like coltan/cobalt, etc or even Nickel. I think it really depends on the type of battery you have.

woow! I love seeing how to recycle electronics and I have never seen anything on that scale or shredding everything together! I love it! I have been collecting electronics for years but I aspire to have a nugget, you have a lot there! I can't believe you don't know about the chemistry part of this. There are many channels that show it. aqua regia and urea I think it is. there are even more precious metals Gold Silver Platinum Palladium Rhodium Iridium Osmium it's crazy what's around us I love what you do! Cheers from Uruguay!

What do you think about using a magnet to separate magnetic metals like iron or nickel before the water with heavy metals enters the buckets? Strong neodym magnets are available at cheap prices.

Would there be any value to crushing the big boards in a multi stage process? I've not used your tools, but I've used crushers before and our processes were optimal only in ranges. We took big bars and crushed them to tiny chunks. Then, in another machine, we crushed the tiny chunks to dust.

From personal experience, you would have to be careful not to grind it all to dust sized fragments. Although the table works by separating the materials by density, even very dense very very tiny fragments can simply be swept away by the water flow required to make the table work. I did a study at our mine mill in an effort to clean up our concentrates. If it had worked, we could have reduced the amount of cons by almost 30% and still retained all of the metals. Unfortunately, our crush size was about 54 microns (think really fine talcum powder) and that stuff would just blow right off the table no matter how slowly we added water from the bars. It was a Palladium and Platinum mine by the way, so really really fine stuff, unlike gold.

Awsome. I Got the idea for my work. Thanks for your video

[@names_churles1263]

I know someone who does this and then uses this green solution I forgot what it is but it separates the gold from the rest of the metal and he makes real good money working by himself.

Awesome Video Jason. Loved it, great small process.

If those were Lithium Ion batteries , there should be lithium somewhere in the mix. Lithium is a light metal, so maybe it's the black stuff. People are looking for sources of lithium to mine recently with the move towards electric cars. It could be profitable to recover it.

The tiny gold wires are from the inside of the chip. They connect the pins to the silicon wafer inside. The outside pins are likely "tinned" with solder.

[@kevinm3349]

do you guys have a lithium battery recycling process? what is needed to recover the lithium and cobalt in the batteries?

[@brettallport1250]

Love your work , much respect from perth West Oz 👏 👍 ...

[@sanfordcarson3941]

The process you use is very efficient

[@zamistro]

What's in the blue buckets on the same pallet as the samples?

[@jsteel89]

I love to see your work. Thanks for sharing!!

"Flat pack" is just a term used for square ic chips with legs on outside edges. Technically they are integrated circuit chips. But there is different types so some people seperate out the square ones
