Method one, dedicated ore haulage craft. Will be designed like space shuttles but probably bigger to improve the economics.

Method two, just tow the asteroid here and mine it on Earth, would require some very precise physics.

Method three, reduce the amount of haulage significantly by processing in space first.

Method one: Shuttle's payload to Earth is 14 tonnes, it might be feasible of you're bringing gold back

Method 2: Yep, seriously precise physics. Gravity is going to have a big influence on thousands of tonnes of asteroid, and I'm not sure what force could be engaged to bring it gently to earth.

Method 3 Processing in space, hmm, maybe but still there's a big mass that needs to come gently to Earth.
