<p>Particles of sand coated with oil are loaded into a housing (1). A fluidising unit (3) is provided towards the bottom of the housing. The fluidising unit fluidises 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, 62) which provides some preliminary separation.</p> |
