PCT No. PCT/GB94/01889 Sec. 371 Date May 31, 1996 Sec. 102(e) Date May 31, 1996 PCT Filed Aug. 31, 1994 PCT Pub. No. WO95/07325 PCT Pub. Date Mar. 16, 1995Particles 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.
