Abstract
A flotation separator has a tank normally partially filled with a liquid, and an endless conveyor belt with upper and lower courses extending from a lower portion in the tank to a higher discharge position exterior to the tank. A shroud isolates the lower course of the belt from the upper course within the liquid, and from the primary circulation in the tank.
