No, a partially flown ticket is a different animal than a wholly unused ticket.
You are governed by the fare rules of your ticket on a partially flown, so you will not simply get half back. After all, a RT may have been less than a OW when you bought. You may get nothing or be able to adjust the return for a fee.
