Well, of course it can. You just crush a little extra for the fuel you burnt. And an astonishing lot of mining equipment is electric anyways, so just buy "green electricity" and all is good. Just as a comparison, we do mine, crush and spread mineral-based fertilizer as a normal part of agriculture. That is of course part of the large carbon footprint of agriculture, but not a big one. So this should be doable. The question I'm rather sceptical about is the areas where one might spread the olivine. How much land it would take, and what the conditions must be. It would be nice if one could just use that olivine instead of gravel in all the parks and on footpaths and stuff.
