I don’t think we’re going to build rock crushers in space. With all that available energy it’d make more sense to just throw the whole rock into a smelter and fractionate the elements as they boil off. Why waste the slag either? You need all the material you can get so hang on to it and use it as ballast or extract the carbon and silicon from it. It’s more likely that we don’t see waste because there isn’t any, a dollar saved is a dollar earned.
