    Thank you for sharing, and showing to other people, that this is NOT way to go, so much mess, poisonous metal solution and acid vapour... some metal scraper (chisel) and hammer does better job, selecting only gold containing stuff. Or hear gun... THEN put into hydrochloric to get rid od solder... Now I see some later your videos doing just that with air hammer... 🙂 Good... I prefer being selective, but whatever you like...

    Take a vacation to the Yukon , pan for gold , outdoors , fresh air , don't forget the bear spray

    A heat gun would be FAR faster and more effective (and a hell of a lot cheaper).

    I would suggest removing any aluminum beforehand just a waste of acid

    This is an interesting idea, but the mixture of metals and materials is going to make the whole thing a right mess. Levering parts off boards that are wet with a metal-laden acid solution while still partially in the solution is not a good idea. The process probably needs to be broken down into more steps, particularly to remove aluminium parts that are going to chew through the HCl first and fastest.

    Cast-iron frying pan with a 1/4 inch of molten solder in the bottom for through-hole. Air chisel on low with a wide blade for surface mount. Faster, no chemicals. Still need a fume hood, though, what with fumes from hot plastic and metal.

    This is definitely one way to depopulate a board. Not one I would use though. I prefer a hammer and chisel. I take what I want then sell the board to the scrap yard.

    This would okay for doin small batches of ram sticks removal of chips and mlccs i assume you could filter the sludge out rreuse the acid for second go instead of discarding it

    This is a very expensive way to end up with a giant toxic stew of just about every contaminate possible inhibiting your precious metal recovery.

    Are chemicals free on your planet? ^^
    Because with this approach you have already wasted up to 20% of the expectable profit on HCl.
    What is next? Blowing the rest on dissolving all the base metals in nitric? ;)

    This is an instructional video of how NOT to refine e-waste for precious metals. With the advent of the internet you would think research would have been done prior to trying this.. lol this is Just plain stupid.
