Technically, Blue Origin did it before SpaceX's Grasshopper.Yes… SpaceX already got there but we do need options so go for it.
Most smelting doesn't require oxygen. You don't want oxygen in it, because that creates oxides, and that's generally bad. That's why aluminum was considered rare a hundred-fifty years ago.
If we can create robots to do smelting in space, there's no oxides. You can use functionally limitless sunlight to melt asteroids into all the metals we could ever want down here on earth. And the toxic gasses can be frozen and put back into the asteroid belt.
