That's true, I'd expect they'd go to our old ruins and scrapyards for ore rather than natural deposits. It's way higher grade anyway. And, they'd have aluminum right off the bat!

They probably couldn't use fossil fuels the same way, which would slow them down, but obviously renewables can work for power. I'd estimate a century or two of additional time to industrialise. For the refining, where they still need to refine, they'd have to slum it with biomass. I wonder if they'd figure out hydrogen refining faster with the different economics.
