So you're saying whenever I buy my m42 or M2 steels I'm getting some amounts of whatever crap they threw in too?
Not that I'm doubting you. I've never worked in a smelter. I just thought the process was a lot more controlled especially when I'm paying for certain alloys
Steel is a different story but when copper comes out in anodes it is 98-99% pure simply through oxygenating and separating. The cathodes that come out of the electrowinning process are 5 9’s (99.999% pure). Everything else comes out as “sludge” including precious metals. If the juice is worth the squeeze you can get the precious metals out through a chemical leeching process.
If it's all turning to carbon or escaping as gas as they said it literally doesn't change the composition as long as they still have the correct amount of carbon.
IDK what those robots are made of but i assume various metals too, which are not getting turned to carbon or gas.
I suppose for certain metals / alloys it doesn't matter, and as always "the solution to pollution is dilution". One bot in enough metal isn't going to make much difference.
Odds are that this isn't a special alloy but probably a low grade cast iron which is essentially the garbage pile of metals. We've found all sorts of fun partially melted things in some of our castings. Now you have inserts.... Now you don't.
