Floating liquids of high viscosity, e.g. heavy oil fractions, may be recovered from a body of water in a pick-up zone (16) by causing the floating liquid to enter apertures (45) in the pick-up portion (26) of a multi-apertured, first recovery member, preferably a chain belt (28). The pick-up portion is moved through a support zone, preferably the lower run (35) of an endless loop (12) of the chain belt running around horizontal rollers (31, 36), in which zone egress of fluid from the apertures is resisted by a second recovery member, preferably a tray (63, 64) beneath the lower belt run. Beyond the support zone, the liquid is expelled from the apertures in a discharge zone, preferably by teeth (50) on a belt drive and discharge roller (36). Preferably, the distance between the pick-up zone and discharge zone is variable. |
