Stripping gold plating from e-waste using Eco-Goldex E-Series 

You shouldn't use powder zinc because it will pre sip out many other things. Use zinc foil or mossy zinc to avoid the problem you are running into. I applaud your vid and thank you for share the very informative scaping tool.

Lol I have you in the background playing while I am doing work, so I hear you talking for like an hour then you say this intro is getting a little long. I actually walked to the computer as I was curious to see how long the video was. LOL I thought it was like one of them 8 hr videos. I am just kidding you do have valuable information, looks like you really know what you are talking about.

Thanks for the info, encouraged me to read up on the cyanide process, how sodium cyanide, potassium cyanide or calcium cyanide compounds with additional oxygen and water (used with the normal Arrhenius equation) dissolves gold fast. I think that anyone handling cyanide compounds without ppe is just crazy. Be safe and keep your pH over 10.5 to avoid creating HCN (boiling point 26 °C;79 °F) while processing.

Just an FYI...., with all the information you just provided about the " Eco Goldex" and that this video is literally encouraging your viewers to maybe go about using this particular product when stripping plated gold from E Waste that you should most definitely send a business proposal to the company for advertising and forwarding clients (Purchasers) their way thus you getting a well deserved profit share with such an informative video. Stay Golden!!

That was a really good and informative video!! I watched every minute and read every caption. It does have a big pro with it getting the gold fast, it also has alot of cons with the extra steps! I look forward to seeing more videos of when you process several kilos of ewaste with your basket!! Have a GREAT Day!!!

Best Eco-Goldex tutorial I've seen so far: very detailed. Still not convinced of the safety of this product for the average Joe Lunchbox, but you have shown what can be done to put those concerns to bed! Well done.

I have seen their videos but was never interested until now. By explaining everything I plan on ordering some now so thank you. They should pay you for this video. As for waste, once you evaporate everything you could pour a little bleach on it just in case there are cyanide compounds. Bleach kills cyanide but I don't know what else is in their product. Cody's lab has a good video on cyanide leaching. Anyways, another great video my friend.

Grazie mille!! Per aver fatto questo video!! Mi a tolto tante dubbi!! Grazie!!!

I just recently purchased some of the eco-gold X the series I was wondering why my solution mixes up clear with a very light yellow tint,after the iron like material settles to the bottom have you noticed any changes to their chemistry I noticed when you mix your compound you got a brownish tint it liquid. I’m glad I stumbled across your videos you do an excellent job.

I've only used this stuff a couple of times now. The gold has to come in contact with the solution. No glue, grease or what ever will stop it from working. With clean gold, it only takes about 30 second to clean the items. My problem is getting the gold out of solution. I just about have that worked out also. Good vid.

Great video very informative thanks for sharing

Thank you for showing this process! :D

M8 cheers on your video. It is filled with good info . Keep up the good work. God bless y'all.

The product placement for the Ford Taurus is impeccable lol. I don’t want to use acids but want to try recovering gold so I might have to give this a go. Thanks

great as always. thank you.

Hello Mr Omega. Arne from🇳🇴Norway here. Tumbs up from me😊. Thank you for tips, and a great clip.

I used to be a cleaner and a salesman came around to sell new cleaning product which was biodegradable, good for the environment and at the end of his presentation. He used to drink some of its straight, to show safe it was. He ended up getting stomach cancer.

On eco-gold e what happens if you have palladium or zinc on parts do they come out in solution

A lot of patience. Watching the whole video is not easy. I still saw, because your words have many important points. My question is, gold recovery percentage in this solution is more or less than other methods?

excellent vid full of useful info just one question what is in the bag that you keep putting in the solution i bought eco from the company for £30 brokers fee was £60 pound total £90 have since contacted a friend in vancouver she has purchased me another bag and is going to post it to the UK for me hopefully cutting down the cost

why didnt you turn end result into a gold button????????

I just got some of this. I'm gonna give it a try! Should I make a video about my experience? I'm a newbie. I'm praying I don't mess up. 1 time I was trying to refine gold with led and end up evaporating 9 grams. It took me almost a year to gather that much. I was so bummed out.. I still am. I gave the universe 9 grams of gold. I pray the universe will reward me with my dreams of being a happy go lucky gold miner.

When you siphon out the liquid, what if you used the tube from an eye dropper stuck into the top end of the hose? It would slow down the siphon process but would reduce the flow rate so you could get it lower without picking up any zinc. You could also make up a clip to hold the tube in place on the beaker wall, so you don’t have to hold it to maintain the height.

So what is the better process, in your opinion, for a beginner. Goldex or the nitric acid process.

Hey man , will it do the gold bonding wires 2?

wonder my friend here i use the gold stripper which is very similar to your product 👍

(Freestyle Libre 2 Sensor ) has some beautiful little (Gold Plated board ) that is a lot of gold just being thrown away………Whenever you get your hands on one, pilled the plastic away and you will see those beautiful little Gold Plated Boards 🤩🤩🤩🤩🤩🤩🤩

Would allowing it to settle in a pressure pot or a vacuum chamber change the bubble situation 🤔

Can you use this product for gold plated jewelry?

How do I get gold out? I have a bunch of this that's dried up because I couldn't figure out how to get my PM's back.

Hey, maybe the pH keeps rising because you're taking minerals in a strong base solution, and getting them to precipitate out of solution by binding it to an acid, creating an acid salt. A citrate, for the citric acid, for instance. So when you remove the acid, by binding it to your metals, from a solution which was strongly alkaline, it tends to drift back towards alkaline.

Where do you buy all the chemicals? Is there an inexpensive kit with everything available?

Oh my god, this method is too complicated. Thanks for the detailed explanation.

I recently learned about the glucose ( freestyle libre sensor patches ), my wife wear them…….She changed them out and throw away, I took one of them and pilled the plastic back…….Discovered some beautiful little ( Gold plated boards inside ) ……These little sensors are just going into trash.

To get it to Western Australia it ended up being around $200aud. $42usd customs charge was disappointing.

A couple of thought I had that might simplify a couple processes; 1. Maybe using LCD finger boards and other flash plated pieces for determining if the ECO solution has achieved peak saturation. They would change color really quickly (like your ph strips) and most are long strips that can be stood up in the beaker and not require pouring out the liquid to remove. 2. Stir plate during citric additions. Maintain agitation of the water column and allow for freer hands to make ph adjustments. 3. Suspend zinc strips in the water during precipitations, with the stir plate active, this would allow you to easily control the weight of zinc going into solution. Question; at this step can you perform acid adjustments while the zinc drop is occurring? I was wondering if you could maintain the ph over a longer timeframe while the first drop is occurring by possibly setting up a slow drip apparatus.. Cheers 🍻

Thunbs Up

Is the third and fourth drops the same method as the second?

Can you tell me exactly how you rinsed all the zinc chloride out of the gold powder. I am having a problem with that.

Wondering if you've heard of using iodine tincture to strip gold. Maybe I'm wrong but it seems simpler and probably cheaper.

How much SMB did you put in with liquid or water in that beaker

I used that so many times, but there are a few defects. 1.it's only strip the gold where the liquids contact the gold plating, anything on the gold plating will not dissolve, it's mean you need to spend more time to deal with it before you strip the gold. 2.if you have a big amount stuff to strip the gold, you have to divide them in a small and strip lot by lot, during that you have to warm the liquids many times. 3.because to make sure all the gold ion is collected which you can't sure that, you need to use more water to clean the all stuff you striped, then boil the water under 1200ml, to make the PH is correct. 4.the plastic is impact the effect, EX. PCBA is the most thing you never want to strip the gold from.

What I'm wondering is, how much gold will it hold? For example: 1 oz of gold can be dissolved in 5 oz of Ar. I know I've done it many times. You had far more solution. I suggest you just keep using it over and over again until it stops stripping gold, then drop the gold. Right now I have about 10 lbs of gold pins, 4500 grams. Using Nitric I recover about 1 gram per 100 grams of pins. To process 300 grams I use about 1 liter of 60% nitric. I need about 15 liters to run the 10 lbs, cost about 600 . I suspect that number could tripple to 30 lbs of pins over the next few weeks. I would love it if I couls use just a few liters of that to strip 30 lbs of pins

I have never done this before, BUT, wouldnt there be Silver and copper in the waste solution?

A couple other thoughts... If you think the gas evolved is CO2 then see if it will put out a match lowered into the beaker. CO2 is heavier than air so you could also slowly tilt the beaker and “pour” some of the gas over a candle flame to see if it puts it out. At least knowing what it is will put your mind at rest. As far as the foaming issue, I wonder if a drop of soap or jet dry could be added as a surfactant without affecting the process? It should lower the surface tension and may help allow the gas to escape? Also I watched another video testing Eco-Goldex on the eScrap Channel, and he made an interesting discovery. He mixed up his solution on a hot plate/stirrer and found all the non-soluble material stuck to the magnetic stirring rod and was removed when he took it out So apparently it contains some iron? It likely contains a ferrocyanide or ferricyanide as it’s active ingredient so depending how they produce it in the kiln there may be some reduced iron trapped in it? In any case it would seem to eliminate the need for the first filtering. Lastly I noticed in the comments of his video someone saying the zinc cements the gold just fine without having to lower the PH? Again if so it may eliminate a time consuming step, then you could still do the second and/or third zinc cementing as recommended and see if it makes any substantial difference?

Hey mate, wanted to let you know I've been using the product a bit here and there. Eco goldx actually recommends using dilute hcl as a replacement for ph adjustment during first cementation rather than citric acid. Either works just fine. Just don't look for the color change from amber to orange as you get close to the proper ph. The second and third ph adjustment still use smb. Also seems to help with the odd precipitate. Ive kept the solution at 40-45c to help keep the excessive air in solution minimal

Seems like it would be better to send the gold plated stuff to me and we split. Given material and time cost and all the finiky stuff your msking 30 cents a hour

What would happen if you had put this container on a stir plate and left a stir stick run all night? You also could have used urea to de nox the AR

I am also curious about the waste product. Thanks for a very informative video.

What do you do if you over shoot the Ph? If it gets too low?

If you took a hammer mill to the chips would this eco stuff strip out all of the gold away from the ceramic and plastic?

Would a small vacuum chamber help remove most of the gases that form?

I've bought some of this stuff how fast does it work on gold fingers

If I do not have a vacuum filter process, will coffee filters work?

Your videos keep getting better and better. Great work. I'm working with a lot of volume and I'm interested in your kiln depopulation basket. Do you have any videos of making it? I've been using an air hammer, and I don't think it's the best method.

You may use NaOCl or H2O2 for the waste solution, to turn CN into N2 and Co2

2 thigs crossed my mind: 1) Weight the electronic parts dry before putting them in the solution, that after the gol is removed dry and weight them again. Wouldn't tht tell you how much gold came out? 2) Abut the foam forming in the gold solution, how about using a vacuum pomp to remove the air bubbles??

You should use a torch to burn off coatings, oils, etc. before stripping.

Can save the zink and reuse it

I found none conclusive sum formula on eco goldex KCN or NaCN or K4(Fe(CN)6) or K4Fe(CN)6 with K2SO4 or K3(Fe(CN)6) Can u tell me what is the sum formula on a Safety Data Sheet ???

I would get an elektronik ph-meter, Bluelab have some good ones for a ok price.

I'm just learning now but couldn't you use aqua regia to remove the gold from metal?

Perhaps there would be no initial insoluble products in your eco mix, if you used distilled water instead of tap water..? Maybe tap water contaminants are the problem, leading to the requirements of multiple Au drops per litre?

I still consider myself a newbie. I haven't actually completed a recovery...still researching and learning processes. Does anyone know of tutorials or videos I can use to learn what the various transistors, Capacitors, transformers chips etc. are in electronics? I want to learn it all now that I'm hooked. Thank you for the videos and I appreciate all help sent my way. This is turning into a great hobby which can generate a little extra $$$ and is good for the Earth if done correct. THANKS

Maybe the county your in has a dump that has a section area for hazmat take a msds copy with you and turn it in there if yall have that

Great video costs to much to get a kilo for uk

Why not place the flask in a vacuum chamber and pull the suspended gases out of solution?

I saw somebody do an extraction on 2 Pentium Pro processors with this stuff. Unless the small quantity of material and bit amatueristic performance it seemed he had yield that could be expected from the 2 components with very little losses.

Thank you for your great videos. I’m really confused by this Eco Gold-x product since everyone seems to be using it differently and some are apparently cutting corners? I’ve watched your video and it seems the procedure the company owner gave you is very complex. I watched another video (don’t recall who) and they didn’t add anything to adjust PH before adding the zinc but he recovered (some) gold. I’ve watched a couple videos by eScrap Channel but instructions he was given were to add NaOH before the zinc cementation, but since that’s a base and if the PH is already at 14 it should really do nothing? Just the fact you and eScrap Channel must have been given different instructions and are using totally opposite chemicals (base versus acid) is confusing, so who is right? Either the PH really doesn’t matter except to prevent release of cyanide gas, or one of you is doing it wrong and probably not getting all their gold? Videos by the owner himself seem just as confusing unless he does steps without showing or mentioning them? You had said you’re unable to test for gold dissolved in Eco Gold-x using stannous chloride solution, even though the company owner told you it should work. If so, you’d really have no way to know you didn’t get all the gold, unless you dissolved a weighed amount of pure gold then checked to make sure you could get back 100% of it from the solution. I would think that is a test well worth doing if you have not done that yet?

To remove the dissolved gas boil the solution. gas dissolves better in "cold" solutions. the warmer the solution the less gas will dissolve in it.

Would putting the first zinc cementing in a vacuum chamber help remove the gas?

can i electrowin the gold after stripping instead of dropping the gold by chemicals

You miss a lot of gold by NOT taking apart the FR connectors. It's worth the time to take them apart.

HAZARDOUS WASTE LIQUID: CONTACT FIRE DEPARTMENT & LANDFILL FOR DISPOSAL INSTRUCTIONS ??

Lmfao i was literally just thinking about the size of the funnel to the flask right before he said it.

You don't need a teaspoon of liquid for a stannous test. That's way to much, and may very well be the reason for crazy results. Just dip a piece of filter paper in the solutoion / barely. Then put just a drop of stannous on the paper

a serious fiasco...? yup ! your right though what to do with great big base metal ?

there still gold plate inside of connectors, you should remove the plastic then strip it so you can get more gold.

Will it strip palladium?silver? Rhodium? As well as gold

Heya bud I'm down this way in Florida as well do you do toll refining?

Neutralizalo con lejia, así eliminas el ferrocianide

You should consult streetips.

Zinc will release hydrogen gas, this hydrogen is coming from hcl. So Zinc is forming ZnCl2, Zinc Cyanate and Hydrogen gas, releasing the gold. This is why the pH keeps rising and it keeps out gassing.

Industrial dose is 240gramm/1m3 1m3 = 1000l 55gramm sound insane lot :)

Your fume hood sounds like it needs a new motor!

Mine turned purple

How does it work with plastic connectors? Does the plastic degrade?

This stuff is kind of like nuclear power. Works pretty good but not sure what to do with the waste.

this seem longer than the aqua regia method this is way more work i will stick to nictric.

Why dont u melt your zinc powder in a frypan or pot. Melt it into metal so u can cut it into pieces then you won't have the problems you have with powder

can you use this process with gold plated jewerly

Like

seems so complicated and more dangerous,

Instead extract gold from the scrap I would rather pick garbage after watched your video for 1 1/2 hours.

You really need to get a answer from the manufacturer. Evaporation is not a answer. What are you putting into the atmosphere?

I posted a Comment can’t seem to find it now I wanted to Edit it I have the RU-vidrs Channel Name. It’s “eScrap-Channel” he’s located out of Bulgaria if that Helps find his Channel to check his Eco-Gold Videos. I’m commenting and giving you his Channel cause he Dissolved his Eco-Gold powder on a Magnetic Stir Plate with Stir Bar. When he filtered it and pulled the Stir Bar out it was Covered in Magnetic Black Sludgy Stuff Sounds and looks like what your Seeing left over. Next time you Have a Chance take a Magnet and record it let me know what happens. Would be nice to See a follow up or Video about this Comment could be an Interesting idea and Video for the Future. Keep up the Hard work and Thanks for The Videos and tip/Tricks.

Real waste, waste can be mixed with cement and then thrown in the trash as the leaching takes 1000 yrs.
