Abstract
Particles of sand coated with oil are loaded into a housing (1). A fluidizing unit (3) is provided towards the bottom of the housing. The fluidizing unit fluidizes the particles and discharges them from the housing to a separator, such as one or more hydrocyclones (8, 14), in which the oil and sand particles are separated. The coated particles can be introduced in the housing (1) via a cyclonic separator (50, 52) which provides some preliminary separation.
