Gold & Silver Recovery From Bulk IC Chips part 1
Вставка
- Опубліковано 6 лют 2025
- In this video series I demonstrate all the steps I use to bulk process large amounts of scrap plastic IC chips and recover the gold and silver they contain. I take steps to maximize the value I get from the chips, and minimize the processing costs. Watch and see... Please visit my blog at mdpub.com/Urban... for more information.

Your processing has definitely become more efficient over the years. Look forward to the result for all your efforts. Thanks for sharing
I'm also an electrical engineer of 10 years (analog instrument design) who has only just gotten into gold recovery, and your explanations during your sorting are extremely helpful. thank you!
I think I've told you this before. I built a rotisserie furnace. Got a kit / set on Amazon for BBQs'. Lined the baskets with stainless window screen. I have a farmers friend brush burner, it sticks inside below the Cage. On the bottom I have a stainless steel tray. As the chips burn they tumble, the ash fall into the tray and the junk stay in the basket. Remove the tray and wash. Done
Do you have a channel with some videos or a walk around on it?
Do u have a parts list and/or link so we can build our own unit? I have 3 foreman rotisserie but want something that I can use to burn off plastic ic chips. Tia
@@wsdsable One last thing, my motor is a varialbe speed
Any chance u have a parts list, or photo? I have a lot of chips and if i could ash them in a basket it would be awesome! TIA @joek511
Nice! Looking forward to seeing the next video!!
can't wait for more!
Hi Mike, Just added 'dutch oven' to my estate sale shopping list! Excellent video - well done! So far it looks like you're doing rather well in the ceramic chip category. You'll need a new 3 ounce mold to pour your gold bar. :) Can't wait for the next video! Thumbs up! Jim
Tolle video, erste video wo ich wirklich verstanden habe. Super erklärt danke!
Look forward to part 2
Great video mate. Think I’m going have to try making myself a ball mill lol
Improves yield. After incineration a lot of the gold gets lockup in the glass fiber and carbon. The mill reduces it to a finer power freeing up the gold.
Excelente
Those power amplifiers can be valuable too. If they work and they’re original.
Mike, I've got two questions (so far):
1. What size range of bearing balls do you use. I'm sure that your smallest ones don't get captured by the vacuum hose.
2. Once you have separated the different precious metals as best you can, how do you sell them? How do you and the buyer determine the actual worth of your ingots? Curious minds.... ;)
Did you retire the weed burner? I am not ready for it yet but used the savings on Cyber Monday to get my new furnace. So I can copy you yet again.
Weed burner is busy burning weeds.
I may need you to come over. Since I think your handful may be larger than mine I am not sure how many to put in.
Why did you change your ashing process? I'm a big fan of your brake line adding oxygen to the hot crucible. Primarily for being smoke free and extremely energy efficient. I only need some gas to get the furnace up to pyrolysis temperature. And from there the carbon in the chips delivers the rest of the heat.
This is just simpler, and I can do larger batches than will fit in my crucibles, and each batch runs quicker. I'm always looking for simpler ways to do things. Sometimes people comment that my methods are too complex for them, or certain equipment or chemicals aren't available to them. It is smokier, but I found with further experimentation that if I preheat the Dutch oven to red heat before putting the chips in, they take flame immediately and the smoke is minimal.
Or quartz tubing for blowing in air. Dual purpose of sparging copper or lead collector during ash smelting
Dónde compraste los chic y cuánto te a costado gracias
Interesting as always, thanks! Do you examine the leadframes and silicon fragments for little bits/blobs of bond wire? I've noticed on some of mine that the bond wire just breaks off the frame/chip and leaves the bonded bit behind, but I'm not doing your process here.
I try to only wash away the finest of the silicon debris. I figure if it is light enough to stay suspended in the water then it probably doesn't have any gold attached to it. I do inspect the metal I sift out for visible gold. I have dissolved all that metal in acid before just to see how much gold I can recover from it. There is some there, but generally not enough to make it worth the time and chemicals to get it. Maybe smelting would be quicker and cheaper. I may explore that in the future.
@@omegageek64 Sounds about right. I'm very interested in trying iodine. It'll apparently start dissolving base metals if it sits too long, but otherwise will only go for the gold. I'm not sure if bromine works the same, but it's not really a feasible choice ;~) Iodine is a bit expensive, but the solution can be refreshed many times, and when it's too contaminated, almost 100% of the iodine can be recovered.
I'm not sure I've ever seen your justification of the ball mill vs grinder. I use a 2.5kg grinder to powder 1kg of pyrolyzed chips in 30sec. I dump that into a dual 14" sieve shaker. I too have about 100lb of DIP chips to process... and i can imagine crushing them 3 handfulls at a time for 2+hrs.
I can set the mill going and walk away to do other things. So time isn't an issue. I can multi-task. I used various types of grinders early on, but got tired of having to replace the blades regularly. The ball mill has been running with no problems for years. It even got flooded in one of our hurricanes this year. After drying it out the balls were all a big mass of rust. I broke up the rust and started it running. The balls smashed the rust to dust and all became shiny again in short order.
Have you ever done a cost study on this process? Can’t imagine you are at a positive cash flow even if you are working for free. In other words, this is a hobby.
Yes, of course it's a hobby. Never claimed otherwise. I have kept track of costs in some of my videos. Sometimes I come out ahead. sometimes I'm in the hole. I don't care. It's fun, and in the end I have gold and silver.
Look budd, you got all the answers, something you haven't realized , if there are 52 people working in a E-waste recycling plant and they produce a 1 pound bar of gold every week of the year you can attribute 1 of those lb to 1 employee named John, if you got the effort you could scrap electronics in your spare time or if you're not working ,instead of sitting in front of the tube, there's 24hrs in a day time that by 7 that's 168hrs a week if you have a 40hr full-time job that leaves you with 128 hrs you're not working, what are you doing for 128 hrs , you can easily subtract 8hrs in that 24 of sleep time subtract that leaves 62hrs, you could get a lot of stuff done in 62 hrs a week, you could subtract for eating and laundry and some necessities
On average it's a 70% to 20% return on high grade electronics.
@toomuchdebt5669 right depending on material
Mike, is the ball mill much better than the Mighty Mill or the Smash-o-Matic for IC chips?
@@WowplayerMe smash o magic is designed specifically for hard rock ore. IC chips would clog it up. Mighty mill is a sampling tool. Not designed for bulk processing. The ball mill works best for bulk incinerated plastic chips.
how do i identify witch one are ceramic and witvh are not, the easy way
It's generally not that hard to tell the ceramic chips from the plastic chips. Ceramic chips are usually made from two hard ceramic plates bonded together with the legs emerging from the seam between the plates. Ceramic chips tend to be a lot heavier than similarly sized plastic chips. Plastic chips are one piece molded from epoxy, usually black epoxy. They also tend to be lighter in weight.
@@omegageek64 someone also once said if u look at them from the side they are usually separated by an adhesive layer usually glass or silicone is that right
@koosduplessis1749 yes.
@@omegageek64 perfect i have about 6kg mixed ic`s i need to process lol
What is the name of that ball mill you're using? I am unable to find something similar with the key words I am using.
I'm not sure my exact model is still sold. Look for vibratory tumblers like this one: amzn.to/3ZyeomK I just added a bunch of big steel ball bearings to it, and instant ball mill.
It's a harbor freight tumbler. Often used for rock polishing
Twelve plus minutes in, and you're finally done INITIALLY SORTING the chips? Mio Dios. Get to it. We don't need the running commentary on EVERYTHING, nor the example shots, nor introductions and rambling bumbling comments when you change scenes.
I believe air bubblers would be less effective than simply adding off-the-shelf hydrogen peroxide, by the way.
You can skip ahead or increase the play speed if you don't like watching certain parts. I liked hearing his thoughts whilst sorting the chips.
@@Alrik. As did I, was very pleasant to me.
I paid once for a cheap air bubbler. Beats continually having to buy peroxide.
Hey mike Awesome video as always, got into e waste a year or two ago as a hobby and bought a propane kiln recently and have a decent amount of IC's saved up.
Do you have a patreon page or a way to email you, learned alot on the videos 🙂
