This number needs to be as small as possible to consider the flotation to be selective. Applying the Lab to the Plant: Obviously if of the feed is sent to conc, a recovery is achieved (without concentration). The idea of selective flotation is to "concentrate" and put as much metal in as little a concentrate mass as possible.
