ABSTRACT:
To avoid using salt in a costly flotation separator process for various products of differing specific gravities, a fresh water flotation system is employed having a controlled buoyancy zone in which an induced current or up-flow elevates the product component of lesser specific gravity causing it to overflow a product conveyor divider member and to settle on that side of the conveyor away from the product component of greater specific gravity. The separation of clam meat from clam shells is envisioned.
