As somebody who spent a vacation taking tours of iron and copper mines, they are kind of interesting. And I've read about mining, and that was kind of interesting too. But role-playing it would be a little like role-playing double entry accounting.

What asteroid mining does to the economy is your own call for the adventure. It's possible that the cost of transportation will not make these metals especially affordable. It's just as likely that their greater availability instead spurs new technology that wasn't possible when these resources were more scarce, and thus maintains the high demand even with the greater availability.
