“sub 3” is nothing* compared to battery acid. Note that 1 pH more or less is a difference of 10x. here pH over concentration, note the graph ends at ~10 %, which is 1/3 of battery acid, but is already below pH 0.
*Yes, technically every value below 3 is included in “sub 3”. But making an upper limit that is a more than 1’000x lower concentration is absurd.
Alright, well I’ll concede that my estimation of pH for battery acid was off - they have it listed at 0.8. I’m accurate with the AMD levels though.
It can get very bad though, like the iron mountain mine article I linked to, where it’s -3.6
With the lower pHs, though, even those around 5, you get metal leaching which quickly becomes a large problem. On top of that, the wastes act as a massive source of both acidity and metals.
I agree. It is just not THAT acidic. The pH will be above 3.5 to be more specific, which is the pH above which Fe3+ can precipitate. Check this pallet for details.
