>>5924657Not that anon, and I haven't heard about this until now, but you can see they're literally just using random scrap metal they've harvested from machinery or some shit. Who even fucking knows what kind of alloy is going into it. Could very well be throwing shit tainted with lead or various other heavy metals in there, and their methods are like if you gave power tools to copper age cavemen.
From a quick google search, separating lead from iron is a hell of a lot more involved than scooping shit out with a big ladle.
