Bravo for the chain mill Engineer! One suggestion if I may- a cheap rectangle "floor vent" from a AC Duct cut to fit the curve on the bottom would be an effective "chute" with a known diameter for an outlet. Great job as always! Thank you for posting!

Yep, great idea, was thinking about doing something like that, if you directed the outlet into a large sealed container, you could then also connect the vacuum cleaner to the container, that would have a nice effect where it would suck air through the machine, meaning you wouldn't get any dust getting out anywhere other than the intended location at the bottom!

could you use the same on ram and pcb board to liberate the gold or do you get gold losses?

great build, thanks for sharing! probably no wear/armor plates necessary for running brass core pins and plastics. i hope it all float seperates nicely for you! i highly recommend Mount Baker Mining and Metals channel to you if'n you're not already watching- search "mbmmllc" i think? you've probably seen how one could make a lower feed height by cutting the feed tube in half, joining the two pieces with a 90, and joining that assembly to the mill with a 135- to prevent ricochet. then again, i like your simple solution tall tube. the pin connectors would just get caught in a 90, unless you had a bigger tube. next project: belt/auger feed hopper!

@successfulengineer

Hey Travis, yep, I get a lot of my inspiration from MBMMLLC, love their stuff! The tall tube seems to work OK, but I do still get a few bits flying out if I don't cover it, I think probably a blanked off tube with feed neck off an angle would be a very good solution. I spent today making a few more tweaks, pretty happy with how it's running now. Next video will probably be trying a few different ways to separate the plastic from the pins, unfortunately the plastic doesn't float and the pins aren't magnetic!

Early thought on separating the output, without knowing the grade of polymer used. Toss that pan full in a bucket of water. I'm thinking the plastic will float and can be skimmed off? Maybe.

Suggestion, if you had an air knife with a variable pressure regulator blowing across the screen in the direction of rotation, the lighter plastic bits would be thrown farther than the metallic bits, thereby seperating more of the plastic from the discharge.

@stanburton6224

This is by the way roughly how U235 was separated from U238 (electromagnetic fields were used instead of air pressure of course) the U238, being ever so slightly heavier was thrown farther due to its inertia than the U235. In this instance we woukd be doing the opposite, the metallic bits, being denser would fall straighter than the plastic...

I never got round to trying this on ICs, would probably do a pretty good job of breaking them up, but might struggle to get them fine enough to release 100% of the bond wires.

U could have cut those pins off with a dremel....put those pins in a vibratory tumbler with glass beads and vibrated until the gold was off the pins...the glass is coated with the gold...it is dark grey...then proceesed the glass after u separate the pins from the glass then you could have hamer milled the other to separate the rest.

Have you ever though about using the cyanidation for gold extraction? I would imagine it should be more practical than the reverse electroplating. You might be required to obtain a prospector's license before you could purchase cyanide though. Or you can make it yourself, but obviously the KZread won't allow a video about a cyanide making.

Hey Chris, I was thinking of doing a "basics" to get started video at some point. My fume hood system is about as basic as they come, a large wooden box with a safety glass sheet on the front that I can lower down if needed. For extraction I just use a sealed-ish 150mm extraction fan that vents externally a reasonable distance away from animals / plants / the house through some 150mm PVC tube. The real trick is to always keep the fumes down as much as possible, I always work with reasonably dilute HCl, and never let acid boil!

Hey@@successfulengineer, thanks for the info! I was thinking about doing something similar, but I wanted to put in pieces of HDPE sheets all around the inside in case their is a spill, nothing gets through, and protects the wood. I was having a real hard time with the ventilation though. I saw some people using a fan that you are describing, but that will eventually fail over time. I was looking for a HDPE ventilation fan, like what would be in an industrial fume hood, but they are like $2-5k each, and I will not spend that.

@successfulengineer

5 жыл бұрын

Yeah, my fans seem to last for a year or so before needing replacement. When I get a new one, first thing I do it completely disassemble it and cover all the metal parts with grease, this provides quite a lot of protection. The base of my box is also HDPE sheet, on top of that I have a large plastic catch container that the hotplate sits in. Then I take things one step further by having a pyroceram casserole dish as a catch container in case a beaker breaks! The biggest single thing you can do to make your extraction fan last a long time is avoid having to move heavy acid fumes. So I like to work with reasonably dilute solutions and also never boil any acid! Good luck, look forward to hearing how you go!

That's a nice mill you built. But wouldn't incineration be much easier?

@successfulengineer

3 жыл бұрын

Pyrolisation / Incineration of epoxy ICs is not too bad for smoke and fumes, but plastic from connectors creates large amounts of toxic smoke. You can try it on small scale for a particular sample if you want. There is a system that turns perform pyrolisation in a sealed environment and extracts liquid hydrocarbon from plastics, that would probably be quite a good way. You would end up basically dust and metal.

I've been trying to extract pins from IC chips using a ball mill but the process is very slow, very inefficient. Your chain mill should be a much better option. I'll be building one soon following your project. Many thanks.

Hey, yeah, I had some luck breaking ICs apart in my "ball mill" (without incineration), but it was very slow going! Mine is really more a crushing mill as it only has 1 large ball. If incineration is possible for you, it is definitely a much better way to go. Otherwise smashing them into 1mm size pieces in a impact mill like this before running them through the ball mill might also be a good idea.

@RODsDIY

5 жыл бұрын

@@successfulengineer Yeah, I think that's a good idea, because with IC's and other chips you need much more crushing power, and a chain slamming against the Bast****s should be better than balls rolling over the material. Maybe if I put a big ball at the end of the chain it would be better.

Try and use a magnet to pick up all the pins if they are magnetic

@successfulengineer

Gave that a try first, unfortunately even a hard drive magnet has no effect on them!

try floating your crushed 'ORE' in soapy water???? The plastics should FLOAT away from your gold laden pins ????

You could have done 2 methods to separate the pins. One is put them on a hot sand bath using a bbq grill with the pins facing the sky so the heat will loosen the bottom and then you can simply pick them up one by one and pluck them out using a plier or whatever. This method is better as you can put alot of pins in the bbq grill. Second method is put the pin slots in a vice grip and get a heat gun and heat it from the bottom part so it loosens and then get a plier and simply pluck the pins out. Works like a treat by takes a bit longer as you have to do it one by one. Hope this helps for next time.
