To extract a thousand tons, estimates are around 6,700 kWh [0]. That’s a bit less than what one of the larger windmills can produce in an hour (7.5 MW). The largest mine I know produces 25.6 million tonnes of ore per year, so (/365/24) three times that. I’m sure we can find room for three windmills over the 16.53 km^2 of that mine.
