Granite extraction and especially treatment, given ore grade, would imply gigantic greenhouse gases emissions, isn't it?
This will be more and more of a challenge even in uranium mines:

- dotancohen 4y agoReplacing much of the equipment with electric, e.g. Tractors and Trucks, would not only reduce the greenhouse emissions during the extraction and refining process, but would also make the equipment more robust and easier to operate. Electric motors generate all their torque at 0 RPM, right where heavy equipment needs it. Contrast with e.g. passenger vehicles which spend very little time accelerating from a quasi-standstill.
- natmaka 4y agoThere is no such adequate equipment. The most adequate electric trucks are way too small. And electric version of various other heavy grinding machines just doesn't exist, AFAIK not even as prototypes. Moreover providing massive amounts of electricity in such remote locations, and also delivering it locally (power cables everywhere in a mine shock-full of heavy equipment? What could go wrong?), is a major challenge. If it's easy for you, then providing all this will quickly get you rich.
