Space Mining: how feasible would it be to catapult the mined materials instead of loading it onto rockets?

For what I understood, there's a minimal velocity required to escape a celestial object... around 11km/s for Earth.

I don't know if this would be feasible on the Moon which is already quite large but let's take anasteroid full of whatever we'd like to get on Earth: How could we get robots to mine it, then throw their findings to Earth's orbit where it'd be routed to land somewhere safe?

What would be required in order to achieve this?

The energy required would be the same. So it's just a matter of whether the energy catapulting the minerals or the fuel for the rocket is cheaper per energy unit output. Also, rockets provide a reentry vehicle. We'd have to design a catapult reentry vehicle. 

Incidentally, the novel "The Moon is a Harsh Mistress" operates on this premise, where a moon colony uses a magnetic accelerator to catapult mined material from the moon to earth.
