    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...

    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.

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

    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

    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? ;)
