Separating Gold From Electronic Connectors Shredded In The Mighty Mill Gold Ore Crusher
HTML-код
- Опубликовано: 6 фев 2025
- Here I once again use my Mighty Mill gold ore crusher to shred some E-Waste electronic connectors to liberate their gold pins. This time I try a gravity separation in water to separate the gold plated pins from the plastic debris. It worked fairly well, but there is room for improvement. There will be more videos starring the Mighty Mill in the future. Subscribe to see them. Please visit mdpub.com/Urban... for more information.

The Mighty mill did a good job pulverising the connectors, but I'm glad you showed us the separation process, I was keen to see that. A denser liquid would be ideal, it would also make the eco-goldex process easier and cleaner. Thanks Mike. 👍
I pan all my connectors this way. i get 99+ % of the plastic and trash out. you cant quite do it like gold panning. when gold panning the rock is much denser then the plastic. shake right to left to get the heavies in the middle.then submerged entire pan and pull pan towards you while moving the pan down in the water. the plastic is light enough that it will float long enough for you to be able to move the pan from under it and the metal will stay. and when i get to the last bit i do not use the ribs side of pan anymore. I turn pan to smooth side and keeping entire pan submerged bouncing it up and down a little while moving back and fourth under the water. the plastic will float under the pan and sink while retaining the pins in the pan still. you will find the right oscillation after trying it a few times. it is like making little tiny waves tub of water that carry the lighter plastic off the pan when you move it downward and towards you leaving the metals in the pan. however you may want to run the material in the mill a bit longer. the smaller the plastic is compared to pin size the easier it is to get rid of it. if you got big chunks with pins in then still they can/will roll out of the pan. that why making your grind into small bits helps a lot.
Those metal shields are actually tin coated copper. I recently pulled a bunch apart and scraped it to make sure.
I use an old kitchen blender to make connector slushies. It's extremely quick, easy and dust free.
Minimise any chunky metal and ensure it's covered with water and the glass jug and stainless blades last surprisingly well.
My plastic lid has a smaller feed hole which is a perfect fit for some big electrical conduit and fittings for a dog-leg feed chute.
I feed mine with a litre of goodies per batch, including every tiny little connector which are easy to drag off PCBs with a wood chisel.
You can pan off a lot of plastic but losses get too high quickly. I look forward to seeing how you get around that.
For now, I just obliterate most of the plastic (and base metals) with strong nitric boils, which is @#$%& messy, but works.
The fastest and easiest way is to pyrolyze connectors. You can then pan all pins out in a few minute. Or simply fill a jar half full with the dry pyrolysis residue, add some water, shake the jar, and decant off the water with the carbon particles (repeat two or three times). This way it's also done in a few minutes. Virtually all the pins are clean and ready for gold recovery, as well as you won't lose a single pin!
Pyrolysis yields fuel oil for the metal melting furnace. The gas generated during the process is led back into the fire chamber, making the pyrolysis run almost self sustainable. The water is recovered by distillation at the next pyrolysis run using the otherwise lost heat in the chimney(free distilled water), and the dry carbon residue is used as fuel for the next pyrolysis batch. Useful minerals to be used for other chemical reactions are extracted from the ash; the rest is fertilizer and/or soil improvement. Absolutely no waste at all.
The other night when I was in the kitchen, it occurred to me that maybe a garbage disposal unit for a sink would work as a grinder.
Hey Mike , would any of the gold plating flake off the pins due to the beating it is getting ?
In a previous video, you said you were looking for ways to process "tonnes of this stuff". If one connector weighs say 7 grams it would take 120 continuous hours to process 1 tonne. must be a better way! Have you thought od chemically extracting the gold plastic housing and all?
Parabéns guerreiro 💎🇧🇷
Did you check the panned off plastic debris for plated pins that made it over the rim of your gold pan?
Hi Mike, Love your gloves! :) I've got an idea?? I'll make a sketch & email it to you. Mighty Mill did pretty good beating the crap out of those connectors! Stay warm! Jim
In the future will you use the mighty mill & separate so that you'd be able to traditional acids in mind?
For those of us who might not be eco goldX users!
I was considering pyrolysing the pins and then washing the ash off. Curious to see if that works or creates a mess….
You yet again impress me... I love these videos of the Mighty Mill. Just one question can you please let me know if you have tried and if not would you try gold finger boards/cards processed thru the mill?
I ask because I have been studying all of your videos and others and the one thing I haven't seen as of yet is what happens to a RAM stick after the finger is removed and after the BGA chips are removed? Does the left over board not get processed? If so would the Mighty Mill be a good way to process them? Anxiously awaiting your comments/reply. Thank you MIke
If those pins are mostly magnetic you could use conveyor belts like MBMMLLC.
Hey!
I'm not sure there is any gold in the flex cables from hard drives and DVDs. Empty work.
Great stuff mike!
It's a shame that the plating isn't heavier, still dud an awesome job by skimming though. Don't freeze .
Maybe run the dirt devil on top of your vacuum and separate lights from heavy
perhaps using your grinder to make it more powder would help,
other option be using a ventilator ...
Run a magnet before panning?
That would pull out the gold plated steel pins, but leave behind the gold plated bronze pins.
@@omegageek64 True, but it would remove and clean the steel ones easily, leaving only the brass ones to be panned.
Use Acid the get ride of the plastic
what about trying a mini sluice
magnets first in separation
After all the stuff has gone thru the mighty mill, why not use a medium sieve to collect the loose pins, then just hit them with HCl + Bleach. Easy Pezy.
HCL and bleach dissolves gold, but not in the presence of base metals. The more reactive base metals will go into solution first making a nasty mess.
